BREAK CHAPTER INTO TERMS; SEAM FINISHES; STITCHES, SEAM TYPES

The following are basic sewing techniques as well as some good tips, listed alphabetically, continued from page 2.

Ribbing


Properly attached ribbing is finished inside and out (no seam showing inside the cuff). Ribbing provides a finished edge and snug fit around a wrist, ankle, neckline or waist, while still allowing flexible movement of the body.

For instructions on properly attaching ribbing, go to our free lesson: Attaching Ribbing.

Seam Finish - How To Finish Seam Allowances

Once a seam is stitched, the edges of the seam allowance must be finished. Pin seams in place before sewing; trim and press open after stitching. Then finish the edges. There are two purposes for seam finishing. The first is to help prevent the fabric edges from fraying. The second is to create a nice appearance.

The first several methods shown below finish the raw edges of the seam allowances separately. The final two methods (binding together and French seams) encase the entire seam allowance, creating a more finished appearance. Binding a seam (encasing both layers) is a very nice way to finish bulkier seams, such as when working with double-sided prequilted fabric. The French seam method is a fabulous way to finish delicate fabrics that have a tendency to fray (sheer curtains for example).

Choose one of the following finishing methods.



Pinking Shears
Pinking shears cut a zig-zag edge on the fabric. "Pinked" means the edge is cut into a zig-zag. This gives a finished look and helps prevent fraying. NOTE: It is a good idea to add a line of stitching inside the pinked edge to add more protection against fraying. pinking shears

Zig-Zag Stitch Seam Allowance

A machine sewn zig-zag stitch sewn along the fabric's cut edge helps prevent fraying. The zig-zag stitch should be sewn close to the edge, allowing the outer zig-zag points to just barely fall over the edge of the fabric. An overcast stitch can be used in place of a zig-zag stitch.

Pink & Stitch Seam Allowance

Pink the edge (using pinking shears), then run stitch a straight stitch 1/4" from the pinked edge.

Clean Finish Seam Allowance

A nicely finished, sewn edge. The edge is hemmed, in other wordsl. Iron under 1/4" along edge of seam allowance. Then iron under another 1/4" and stitch close to the edge. This method prevents against fraying and provides a finished appearance.

Tricot Bound Seam Finish

Tricot tape is lightweight, and is stitched around the seam allowance edge. It can be applied to fabric BEFORE the seam is stitched. I recommend this if the fabric is especially prone to fraying. It can be found under names such as Seams Great™ or Seams Saver™. Each seam allowance is bound separately. Stitch the seam, press it open, then curl the tape around the edge of the seam allowance (gently tugging on the tape will encourage it to curl around the edge). Use a straight stitch or zig-zag stitch to hold the tape in place, stitching through all three layers - top tape layer, fabric, bottom tape layer. For fabrics that fray easily, use a zig-zag stitch.

Binding Seam Allowances Together

Binding is stiched onto the seam allowance in the same way that it is stitched around a quilt or placemat. The raw edges are totally covered - together. Rather than finish each edge separately, the edges are placed together and the binding encloses the two layers together. Use this method for heavy fabrics, such as very heavy denims or other bulky fabrics. It can also be used for delicate or lightweight fabrics.

French Seams

By totally encasing the seam that holds the raw edges within a second seam, the raw edges are protected. The second seam provides a backup to the first seam. The inside of the garment or other item is nicely finished; there are no raw edges showing.

1.  Stitch seam with layers WRONG sides together. Fold back fabric layers so that they are now right sides together, with seam allowances between the two layers.

2.  Stitch a new seam so that the first seam edges are totally inside the new seam allowance.

Sewing / Embroidery Stitches / Seam Types (move)

Basting

The purpose of basting is to temporarily hold fabric in place until the permanent stitching is in place. Example: Baste a seam that will later hold a zipper. For a center back dress zipper, the back of the dress is made in two halvs. A center back seam is sewn from the bottom of the dress up to the point where the zipper will be installed. From that point up to the top, the seam is basted. This holds the seam edges in place until the zipper in installed. The basting is removed once the final stitching is completed.

Double Stitched

Double stitching a seam provides a "back-up" for seams that need to withstand extra stress. It also provides a seam finish for fabrics that tend to fray. Stitch the seam, but DO NOT press the seam open. Instead, stitch a second line 1/8" from the original line of stitching (INSIDE the seam allowance). The second line of stitching can be a straight stitch or a zig-zag stitch. Zig-zag stitches provide more protection from fraying. Trim close to the outer line of stitching.

Lapped Seam

This type of seam is used only of fabrics that do not fray. They are suitable for heavy fabrics such as suede or leather, or faux suede or leather. The fabric layer that is to be the upper layer is trimmed closely to the edge. Place the upper layer over the under layer, both right sides up, overlapping the edges. Stitch close to the trimmed edge of the upper layer, and again 1/4" from the first line of stitching.

Embroidery


Hand Embroidery Stitches
Hand embroidery adds a beautiful finish to items. Embroider a quilt; add decorative embroidery to tote bags, apparel, pillowcases, placemats and just about any other item you sew. See our Free Embroidery Glossary for a fully illustrated, alphabetized list of embroidery stitches.

Free Motion Machine Embroidery
Free motion embroidery can be done with any machine that has zig-zag capability. A darning foot is used, the feed dogs are lowered, and your hands guide the fabric under the needle. It is easy to learn. A stabilizer must be used to add body to the fabric. Learn how to use your sewing machine and a darning foot to create beautiful free motion machine embroidery with our lesson on Free Motion Machine Embroidery.

Flat Felled Seam

This type of seam provides a finish both inside and out. It also creates a very strong seam. Stitch a seam line. Press the seam allowances to one side. Trim the bottom seam allowance to 1/8". Turn the upper layer seam allowance under 1/4" and wrap it around the edge of the lower layer seam allowance. Baste it into place with a machine stitch or pins. Stitch the seam allowance to the garment, using an edgestitch (stitch close to the edge).

Gathering

Gathering can be done by hand or by machine. Most people find it easier to use the machine. The gathering stitch, like the basting stitch, is an extra long, straight stitch.

Gathering is done to ease in fabric along curves, such as when sewing in sleeves, and for adding fullness, such as with curtains. The gathering can be very subtle (just enough to ease in the sleeve) and not show along the seam, or can be much fuller, such as for a puffy sleeve or a skirt. The permanent stitch is placed right on top of the inside gathering stitch (away from the fabric edge).

An important note in gathering: Proper gathering for full skirts or puffy sleeves calls for two lines of gathering stitches (gathering for use in gently easing in a sleeve uses only one gathering line). Don't omit the second stitch line! The second stitch line serves two important functions.
  • It is a back-up in case the first line breaks.
  • It makes for a much nicer row of gathers. They are easier to control in spacing, and have a much tighter, rounded appearance, instead of a flat, folded look.

Hem Stitch

See Quick Index at top of page for link to hem stitch page.

Stay Stitching

Stay stitching is used to prevent stretching and fraying in fabric. Stretching can occur when handling and sewing curved areas. Fraying can occur where curves are clipped. Start at the edge and stitch to the center. Repeat on opposite side.

Stitch Locking

When sewing any seam, always lock the stitch at both ends. To do this, sew in reverse at each end. This will hold your seam, so it does not come apart at the ends.

Topstitching

Topstitching refers to stitching done on the top side of the garment. In other words, it shows. It serves two main purposes. It can be a straight stitch, zig-zag or any other stitch you choose. If a straight stitch is used, it is usually done with a slightly longer stitch length.



1.   Hold Seams Flat
It is used to hold seams down flat, such as topstitching around the sleeve or waistband seam.

2.   Decorative
Use topstitching to add a decorative touch to a garment. Make it more noticeable by using contrast thread color.


Your machine may have several decorative stitches to choose from. The photo below shows several decorative stitches available on a Pfaff sewing machine. decorative stitches
Straight stitch topstitching is usually done close to the edge. The example on the right shows a place mat with topstitching 1/8" from the edge.

Stitch Length and Width (from Chapter 5: Setting Up Your Machine)

Stitch length refers to how long each individual stitch is.

Regular   11 - 12 stitches per inch

Basting    6 stitches per inch (i.e. a longer stitch, so fewer per inch)

Gathering  6 - 8 stitches per inch

Generally, heavier fabrics work best with a longer stitch length, and finer fabrics are best with a shorter stitch length. Proper stitch length is important and is a first place to start if you do not like the look of your stitching. For example, a slightly puckered seam in the fine fabric could be caused from too long of a stitch length - the feed dogs are feeding too much fabric through each stitch, making a puckered look. To correct this, a shorter stitch length should be used (also check tension - more on this later).

Remember that the higher number of stitches per inch translates to a short, tighter stitch.

Stitch width refers to how wide the stitch is. A regular straight stitch has no width, but a zig-zag or decorative stitch can be set to any number of widths.
