Backstitch 

Backstitching is most commonly used at the beginning and ending of seams to lock the 

stitching so it does not come undone.  Start sewing the beginning of the seam about 3-4 

stitches, then sew in reverse for 3-4 stitches. Start sewing forward again and continue 

sewing the seam to the end, then sew in reverse 3-4 stitches, then forward again to finish.

Basting 

Basting is temporary stitching, sewn using a long straight stitch and reduced tension. This 

temporary stitching holds fabrics together, but is intended to be removed. For example, 

basting the side seams of a skirt to check the fit, then the final seam is sewn and the basting 

stitch is removed.

In order to sew small, tubular projects such as a pant leg, sleeve cuff, etc, you will need to 

take the removable storage compartment off the machine, giving access to the free arm.

Interfacing 

Interfacing is specially designed material, sewn between fabrics, used to provide additional 

structure to parts of a garment, for example, cuffs, collars, plackets, etc. It can be used for 

buttonholes to help keep the fabric stable while sewing.

The raw edge of the fabric refers to the cut edge and usually becomes the edge of the seam 

allowance. 

Seam 

A seam is stitching that joins two fabrics together, includes the main stitching line and the 

seam allowance.

The seam allowance is the amount of fabric between the seam stitches and the raw edge of 

the fabric. The most popular seam allowance are 5/8” and 1/2”.

Seam Finish 

Seam finishing is stitching used to keep a raw edge from unraveling or fraying.

Stabilizer is special material used to provide additional support for stitches for special 

techniques such as decorative machine stitching, appliqué, buttonholes and more.

Topstitching 

Topstitching is straight stitching that appears on the top side of the fabric, used for adding 

strength, embellishment or both.
