Needle thread tension

To ensure a perfect sewing result the needle and bobbin thread tensions must be perfectly tuned to each other. The normal setting for utility stitches is between 4 - 5.

Check the tension with a broad zigzag stitch. The threads must be interlaced between the two fabric plies.

If the needle thread tension is too high, the threads are interlaced above the top fabric ply. If the needle thread tension is too low, the threads are interlaced below the lower fabric ply.

The adjustment of the bobbin thread tension is described on page 15.

Topstitching with the edge guide (special accessories)

For broad topstitching work we recommend using the edge guide. This accessory guarantees topstitching which is parallel to the edge of the fabric. The edge guide is inserted into hole C and held their with retaining screw F.

Basic straight stitch with needle position "left" (only models 4260 and 4250)

Some sewing processes can be carried out more easily by altering the needle position. E.g. topstitching a collar or sewing on a zipper.

Model 4260:

- Select straight stitch E and set the stitch width adjustment button (7) to "0".

Model 4250:

- Select stitch F.

Please ensure that the needle is at its highest position when adjusting its setting.

Zigzag stitch

Model 4260:

- Select stitch F. With the stitch width adjustment button (7) you can vary the width between 0 and 5 mm.

Model 4250:

Select stitch G.

Model 4240:

Select stitch F (2 mm) or G (4 mm).

Blind stitch foot no. 3 is particularly suitable for serging difficult materials. While sewing, the thread passes over bar C thus preventing the fabric edge from rolling up. This ensures a good, smooth seam.

The trimmed edge must be guided along stop B. You can adjust the stop with retaining screw A.

Be careful to ensure that when serging the fabric edges the needle perforations alternate between entering the fabric and next to the fabric when overstitching.

Elastic blind stitch

The elastic blind stitch is especially suitable for invisible hems; sewing by hand is no longer necessary. It is equally suitable for both stretch and non-stretch fabrics.

The hem is sewn and serged simultaneously. i.e. an extra serging of the fabric edge is not necessary.

• On materials which fray strongly, serge the hem edge separately.
• Fold the hem width inwards.
• Now lay the hem back outwards so that the hem edge protrudes by about 1 cm.
• Now lay the fabric underneath the presser foot so that the crease line runs along the red guide.
  — The needle must catch only one texture yarn when entering the fabric in the crease line.

Sewing on buttons

For sewing on buttons, the presser foot must be removed and the feed dog must be covered with the darning plate.

• Select the 4 mm zigzag stitch (model 4260: stitch F, stitch width adjustment button at 4: model 4250 and 4240: stitch G)
  — Turn the handwheel towards you and move the button in such a way that the needle enters the right hole in the button.
• Now lower the presser foot lifter; this holds the button off the blade.
• Now sew on the button. Take care to ensure that the needle also enters the right hand hole in the button.
  — Knot the thread ends on the reverse side.

Sewing on buttons with a button shank

• Insert the presser foot.
  — Place a match between the holes in the button and sew as described in the left hand column on this page.

Stretch triple straight stitch

With this program, all seams which require a high level of durability are sewn: e.g. crotch seams.

Stretch triple zigzag

The stretch triple zigzag is a very elastic and decorative seam which is particularly suitable for T-shirts and underwear.

• Serge the fabric edge.
• Fold over the desired hem width.
• Topstitch the hem from the face side.

Elastic stitch

Because of its high elasticity, this stitch is used for sewing on elastic band, e.g. on underwear.

• Cut off the old elastic band close to the fabric edge.
• Gather the fabric with the 4 mm long straight stitch (c.f. page 40).
• Slide the workpiece between the elastic band or lay it underneath it and pin it down.
• Sew it on using the elastic stitch. Allow the ends of the elastic band to overlap a little and overstitch with the elastic stitch.
• On skirts and trousers, the elastic tape is sewn onto the edge which has been prepared as above, using the elastic stitch.

Honeycomb stitch

The honeycomb stitch is an elastic and decorative hem which is particularly suitable for hems on underwear and T-shirts.

- Fold the hem over double and overstitch it.

What is an overlock stitch?

For elastic and knitted materials, the hobby models 4250 and 4260 offer overlock stitches which sew two fabric layers together and serge simultaneously. They are more elastic than normal seams, very durable and easy and fast to sew.

Tip: We recommend using blind stitch foot no. 3 when sewing overlock seams. It guides particularly well and prevents the seam puckering even on broad seams.

Stitch K stretch

(only models 4250 and 4260)

Closed overlock stitch

With this stitch you can sew jersey quality perfectly. You can also sew on sleeve cuffs and knit collars.

Tip: Ensure that the sleeve cuff is stretched while it is being sewn.

Stitch L stretch

(only on models 4250 and 4260)

Open overlock stitch

With this stitch, thicker materials and fabrics which do not fray strongly can be sewn together perfectly.

Tip: Ensure that the needle sews the right hand stitch just next to the material and not in it.

Spring stitch

With the spring stitch you can sew elastic materials with an effect similar to that of hem stitching, e.g. corsetry. The benefit of this stitch is that the seam lies flat.

• Serge the fabric edges and baste them over.
• Lay the edges to be sewn underneath the pressing foot at a distance of about 3 mm.
• Overstitch from the reverse side, ensuring that the needle perforates the material both right and left.

Buttonholes

Sewing buttonholes is very easy with all of the hobby models because the fabric does not have to be rotated. To make sewing buttonholes even easier we recommend the buttonhole foot (special accessories).

Generally, buttonholes are sewn into lined, doubled fabric. However, it is necessary to additionally line some materials such as silk, organza and viscose with backing paper so that the fabric does not gather when being sewn.

Avalon (from Madeira) is also very good for this purpose. This is a special type of fleece which dissolves in water. On materials such as velvet and thick wool fabrics which feed poorly it can be used either on or underneath the fabric. The material is thus fed more efficiently by the machine and buttonholes are much easier to sew.

Embroidery and darning threads are particularly good for sewing attractive seams.

Using a magic marker or pin, mark the starting points of the buttonholes and always sew a test buttonhole first.

Note:

Before every buttonhole you must slide the runner of the buttonhole foot (special accessories) forwards as far as it will go, i.e. the red arrow is at the first red line. The red markings are 0.5 cm apart. They give you a yardstick for determining the length of the buttonhole.

Linen buttonhole

• Insert the buttonhole foot and slide the foot forwards as far as it will go.
• Position the pattern adjustment dial at B and sew the first buttonhole seam in the desired length.
• Then, with the setting AC, sew a few stitches for the bartack. You have to hold the fabric while doing this.
• Then select the letter D and sew the second buttonhole seam in the reverse direction and in the same length.
• Then set AC again and sew a few bartack stitches while holding the fabric.

Model 4240:

Knot the thread ends on the reverse side.

Model 4250:

- Adjust to the straight stitch setting F (left needle position) and sew a few tying off stitches.

Model 4260:

• Adjust the setting to straight stitch E and select the left needle position by turning the stitch width adjustment dial (7) to 0.
• Saw a few tying off stitches.
• Cut open the buttonhole with the aid of a pair of scissors or a slitting knife.

Linen buttonhole with gimp thread

To sew especially durable buttonholes, e.g. on sportswear, we recommend using a gimp thread.

On elastic materials the gimp thread is particularly important to prevent the buttonhole from stretching.

• Lay the gimp thread over the rear protrusion A and pass the thread ends underneath the presser foot towards the front.
• Clamp the threads to the left and right of protrusion B.
• Slide the buttonhole runner as far forwards as possible and sew the buttonhole as described in the left hand column.
• Pull the loop of the gimp thread into the buttonhole and cut the threads.

Linen buttonholes

• Mark the beginning and end points of the buttonholes on the fabric.
• Proceed as described in the section "Sewing buttonholes with the buttonhole foot".
• When sewing the second buttonhole seam, do not sew further than the beginning point.

Hem with the twin needle

Topstitching work can be carried out on normal and stretch Materials with the twin needle.

Professional hems on T-shirts, knitwear and cycling shorts can be sewn quickly and easily with the twin needle. The twin needle is available in various widths. Please ensure that you use the jersey needle for stretch fabrics!

The twin needle must not be broader than 3.5 cm when sewing with the straight stitch (with the zigzag stitch not more than 2.0 mm) to avoid needle breakages.

• First iron over the width of fabric desired for the hem.
• Then topstitch the hem from the face side.
• Finally cut the protruding hem edge back to the seam.

Tip: On difficult materials such as ribbed knit-wear it is advisable to baste the hem before topstitching it.

Threading the twin needle

• Place a spool on both of the spool stands.
• Simultaneously pass both of the threads through the thread guide marked with the arrows. In the right thread slot, one of the threads must pass to the right and the other to the left of the tension disc C.

Smocking effect with elastic threads

Fine, light fabrics such as Batist, viscose and silk are especially suitable for beautiful smocking work. For smocking work with the elastic thread you should use an additional bobbin case and wind it by hand with the elastic thread. As the elastic thread is much stronger than the normal bobbin thread, the tension of the bobbin case must be set at very low. Don't forget however, the higher the bobbin thread tension, the more intense the gathering effect.

• Sew a test seam to determine the level of gather.
• Mark the first line on the face side of the fabric and sew along it.
• Each additional seam can be sewn at a presser foot's width from the first row.
• When sewing several seams next to one another, you must stretch the fabric to its original length when sewing the subsequent seams. Otherwise the gather will be irregular.
• Knot the threads at the beginning and end of the seam on the reverse side.

Gathering with the straight stitch

With the program E you can gather sleeves, skirts and valances with a stitch length of 4 mm. To ensure a regular gathering effect you should sew two or three rows of gathering.

• Mark the first line on the face side of the fabric and sew along it. Allow the threads to protrude approx. 10 - 20 cm.
• Each subsequent seam can be sewn one presser foot width from the last.
• Gather the piece of fabric by pulling the bobbin thread. You determine the amount of gather by how much you pull the thread.
• Finally the thread ends are knotted to secure the gather.

Gathering with the elastic thread

Sleeve and waist seams can be gathered with ease using an elastic thread. The elastic thread does not have to be wound onto the bobbin.

• Mark the first gathering seam on the reverse side of the fabric.
• Sew a few stitches using the honeycomb stitch and leave the needle in the fabric. The needle must be in the middle of the presser foot. Raise the presser foot and lay the elastic thread around the needle.
• Lower the presser foot and sew a few stitches. Then pull the elastic thread evenly at both ends.
• You determine the amount of gather by the amount you pull the threads.
• The gather can also be altered after sewing by pulling the ends of the elastic threads.
• Finally, knot the threads and the elastic.

Tip: The cording foot (special accessories) is particularly suitable for gathering. Due to its guide grooves the elastic is fed evenly during the sewing process.

Darning with the elastic stitch

Darning with the elastic stitch is especially suitable for repairing damaged areas.

- Sew over the damaged area in rows until it is well covered. Take care to ensure that the rows overlap.

Sewing on patches

To cover larger holes well, it is necessary to sew a new piece of fabric onto the damaged area.

• Baste the new piece of fabric onto the damaged area of the face side of the fabric.
• Sew over the fabric edges with the elastic stitch.
• Now cut the damaged area back to the seam from the reverse side of the fabric.

Tip: To simplify turning the corners of the patch, turn the handwheel until the needle is in the fabric. Then raise the presser foot and turn the fabric.

Repairing tears

On tears, frayed edges or small holes it is useful to lay a piece of fabric under the reverse side of the fabric. The underlayed fabric reinforces the workpiece and ensures you a perfect repair.

• Lay a piece of fabric underneath the material. It must always be a little larger than the damaged area.
• Now sew over the damaged area in accordance with the size of the tear.
• Cut the underlayed piece of fabric back to the seam.

Sewing on zippers

There are various methods of sewing on zippers. For skirts we recommend the bilaterally concealed zipper, for men's and ladies, trousers the unilaterally concealed zipper. The market offers various zippers. We recommend using a metal zipper for strong fabrics such as denim. For all other materials we recommend a plastic zipper.

It is important for all types of zipper to sew very close to the edge of the teeth of the zipper. This is why it is possible to insert the zipper foot either on the right or the left of the presser foot holder.

If the zipper foot is inserted into the left side of the presser foot holder you can additionally use the needle position "left" on models 4250 and 4260.

Bilaterally concealed, sewn in zipper

• Insert the zipper foot on the right hand side.
• Baste in the zipper and lay it underneath the presser foot so that the teeth of the zipper run alongside the foot.
• Stitch in half of the zipper, leave the needle in the fabric, raise the presser foot and close the zipper.
• Now you can continue sewing the seam up to the end of the zipper and sew the lateral seam.

Black-and-white photo of a sewing machine needle stitching fabric, no visible text or symbols

• Sew the second half of the zipper parallel at the same distance.
• Stop after the first half and leave the needle in the fabric. Raise the presser foot and open the zipper.
• Now you can finish sewing the seam.

The trouser zipper

• Iron over the seam allowances, taking care to ensure that the underlap protrudes by about 4 mm.
• Baste the zipper under the underlap so that the teeth are visible.
• Insert the zipper foot on the right hand side and move the needle to the correct position.

• Sew along the edge of the zipper.

• Just before the end of the seam, open the zipper and finish sewing the seam.

• Close the zipper and baste the overlap evenly to the other half of the zipper.
• Then sew through the basted seam.
  Tip: To achieve a perfect seam, we recommend using the edge guide (special accessories).

Stabilizing edges

With the hemmer (special accessories) you can stabilize blouses, silk cravats and valances with ease, without having to pre-iron the fabric edges. The hemming prevents the edges from fraying and a clean, durable edge is the result.

• Fold the beginning of the fabric edge over twice (each approx. 2 mm).
• Lay the folded fabric edge underneath the hemmer and sew a few stitches with the straight stitch E. Stitch length 2.5 - 3 mm.
• Leave the needle in the fabric, raise the presser foot and insert the hemmer foot scroll into the fabric.
• Lower the presser foot and guide the fabric edge evenly into the hemmer. Take care to ensure that the fabric does not run under the right half of the presser foot.

Inserting lace

You can achieve a beautiful effect by inserting lace, e.g. on baby and children's clothing.

• First the lace is basted onto the face side of the fabric.
• Sew on both sides of the lace at a narrow margin.
• The fabric underneath the lace is cut down the middle and ironed to the side.
• Sew over both edges of the lace with a small, dense zigzag stitch.
• Cut back the extra fabric.

Attaching lace

You can beautify and remodel home textiles with an appropriate lace over and over again.

And here's how it's done:

• First serge the cut edges.
• Sew the lace onto the face side of the fabric up to the first corner.
• Fold the corner and sew over it diagonally.
• Process all the following sides in the same way.

Shell edging

The shell edge is especially attractive on thin, soft fabrics such as silk and viscose. It is often used as an edging on underwear. The higher the needle thread tension, the deeper the shell edge feed.

• Serge the fabric edge and iron over the seam allowance.
• Take care that the fabric only runs half underneath the presser foot while sewing. This intensifies the effect of the shell edging.

Tip: By sewing a coloured woollen thread into the seam you strengthen the shell edge while also creating an attractive contrast in the seam. A fine fabric of another colour can also be used instead of a woollen thread.

This especially artistic form of eyelet and insert embroidery is easy to sew with your sewing machine.

• Using a magic marker, draw your motif onto the face side of the fabric.
• Then place two layers of Avalon fleece underneath the parts to be embroidered and clamp both the fabric and the fleece into an embroidery frame.
• Insert foot number 0.
• To lend more durability to the embroidery, sew all of the contours twice using the straight stitch (stitch length approx. 1 mm).
• Then carefully cut out the fabric from the areas which are to be hollow, 2 mm next to the contour. The fleece must not move.
• Embroider the contours with a dense zigzag stitch.
• Due to the embroidery fleece, this part of the work is much more stable and strong.
• Finally, simply dissolve the embroidery fleece in cold water and your one-off design is finished.

Patchwork quilt

Patching and quilting are traditional handicraft techniques which were originally used by north American pioneer women to make use of leftover fabric. Over the years it has developed into a creative hobby.

Patchwork quilts used to be sewn exclusively by hand. Nowadays, however, you have the possibility to make your creative ideas a reality in a much shorter time.

A patchwork quilt always consists of three layers of fabric:

A number of geometric pieces of fabric are combined in different variations to create a patchwork which forms the top of the quilt. This is then basted to a fleece layer and then sewn onto the back of the quilt which usually consists of one piece of fabric. The entire quilt is often bound by this bottom layer.

And here's how it's done:

• Using your own or commercially available templates, cut the pieces you need for your patchwork. The templates should include a seam allowance of 1/4 inch (0.63 cm).
• Spread these pieces out in front of you in accordance with the pattern and form small squares which you can then put together. These squares will then be sewn together and will form the top ply of the quilt.
• The seam allowances are not serged when quilting, but rather they are to be smoothed down, never ironed!
• Baste the finished top ply of the quilt onto the fleece insert and the bottom quilt layer.
• Traditionally, these three fabric layers are sewn together with small manual stitches - this procedure is faster and more practical with a sewing machine, e.g. with the straight stitch or the program I stretch (only on model 4260). Always sew approximately 3mm next to the seam. Use foot number 0 or the quilt and patchwork foot (see page 58).

You can then continue to sew your quilt, making it into a cushion, a wall hanging or a bedspread.

Hemstitch seam

The hemstitch seam is an old embroidery technique and can be used to secure edges on table linen as well as for decoration on clothing. For your hemstitching work you will require a wing needle and coarse linen out of which you can easily pull the single threads. Furthermore, the darning and patching thread is particularly suitable. With the stretch zigzag stitch you can sew various hemstitching techniques such as the wale hemstitch seam, a hem sewn with the hemstitch and a hemstitch seam as an edge. Use the normal presser foot.

Wale hemstitch seam

• As with the hand hemstitch seam the threads are pulled out to the desired width.
• Using a narrow stretch zigzag stitch, sew along both of the fabric edges. The needle must perforate the area of the pulled threads just next to the edges. This bundles the threads.

Hem edge sewn with hemstitch seam

• Iron the hem over twice and pull one or more threads out from above the hem.
• Using the stretch zigzag stitch, sew the hem from the face side. The needle must perforate the hem on the right hand side and bundle the pulled threads on the left hand side.

Hemstitch seam as edge

This edge is used for very fine, thin materials. It is particularly suitable for valances and ruffles. No threads have to be pulled.

• Using the stretch zigzag stitch, sew at a presser foot's width along the edge of the fabric.
• Using a small pair of scissors, trim off the excess fabric on the hemstitch edge.

Bias-tape binder

Binding with a bias tape is a simple way of lending fabric edges a smooth, clean appearance. You will need: bias tape, 24 mm wide, unfolded.

• Remove the presser foot and the presser foot holder and screw on the tape binder.
• Cut diagonally across the beginning of the bias tape.
  – Guide the tape into the pouch of the tape binder and pull it out towards the back.
• Set the tape binder in such a way that the needle perforates 1 - 1.5 mm from the folded bias-tape edge or alter the needle position.
• Sew a few centimeters along the bias tape with the straight stitch before laying the trimmed edge which is to be bound into the slot of the tape binder. The trimmed edge must be inserted between the band. The bias tape automatically wraps around the edge of the fabric automatically during the sewing operation.

Tip: You can achieve an additional effect by using the zigzag stitch.

Multi-stitch gathering attachment

The classic of all the presser feet! You have the choice of whether you wish to lay dense or broad pleats. The multi-stitch gathering attachment offers three options for use:

1. Laying pleats in fabric.
2. Laying pleats in fabric and sewing them simultaneously.
3. Laying pleats in fabric and sewing lace onto them simultaneously.

The foot comes with a detailed description when you buy your multi-stitch gathering attachment at you PFAFF dealer.

Felling foot

Felling seams are decorative and durable. Therefore, they are especially suitable for sportswear and children's wear, men's shirts and jeans. These seams are particularly attractive when you use sewing threads of contrasting colours.

• Lay the pieces of material together, reverse side to reverse side.
• Let the trimmed edge of the bottom ply protrude by about 1 - 1.5 cm.
• Now lay this protruding edge over the tongue of the felling foot. The fabric must be laid totally under the presser foot.
• Now sew over the folded edge with the straight stitch (stitch length 2.5 - 3 mm).
• Then pull the fabric layers apart and insert the raised hem into the felling foot. The hem is folded over by the foot and the edge is sewn over. Pull the pieces of fabric apart while sewing them.

Single-needle cording foot

Cording is a technique by which an embroidered purl seam results from embroidering over bead yarn or a fine filler cord. This allows you to achieve a similar effect to that of soutache braiding. This raised purl seam also makes appliqué work more expressive.

• Draw the desired motif onto the fabric. Try to avoid tight curves and sharp points.
• Insert the single-needle cording foot and lay the gimp thread into the front left groove of the presser foot. Then lay the gimp thread into the rear groove under the sole of the presser foot.
• Using the stitch-pattern adjustment knob (24), select the buttonhole symbol B. Set the stitch length to the "Buttonhole" symbol.
• Now stitch over the gimp thread with the narrow, dense zigzag stitch. The so-called purl seam results.

Tip: You can achieve a special effect by embroidering over a medium sized bead thread with a sewing thread of a different colour.

Knit-edge foot

As the knit-edge foot has two presser foot soles of differing height, thick knitted fabrics can be sewn with ease. To do so select the open or the closed overlock stitch. To ensure a perfect seam on fashioned workpieces, we recommend sewing a woollen thread under slight tension along with the thread while simultaneously sewing over it.

Quilt and patchwork foot

When using the quilt and patchwork foot, always sew the pieces of fabric with the required seam allowance of 1/4 or 1/8 inch because the distance from the needle to the outer right edge of the foot is 1/4 inch (0.63 cm) and to the inner right edge 1/8 inch (0.31 cm).

Patching

• Insert the quilt and patchwork foot.
• Sew the pieces of fabric together with the straight stitch. When working with 1/4 inch seam allowance, guide the piece of fabric along the outer right edge of the foot. When working with 1/8 inch guide the fabric along the inner right edge of the foot.

Quilting

(sewing through the top layer, fleece layer and bottom layer of the quilt)

- Sew the three fabric plies (e.g. with the straight stitch) approx. 3 mm next to the seam (see page 51).
