What is a Stitch?

A stitch is a loop of thread made by a needle, which pulls it through fabric to create a stitching line.

A stitching line is a sequence of stitches that usually holds two pieces of fabric together (or more). 

Depending on the fabric quality and the purpose of the seam, you can use different stitches: lock stitch, chain stitch, overlock stitch, cover stitch, etc.

What is a Topstitch?

A topstitch is a stitching line that is visible from the right side of the fabric.
Its function can be either ornamental, as well as to reinforce the seam and keep the seam allowance stable.

What is a Seam?

A seam is the result of sewing a line of stitches.

The purposes of seams are:

  • join two or more pieces of fabric
  • make a finishing on the edge of a fabric
  • attach a material (a piece of fabric or trim) on top of another fabric
  • modify the volume of the fabric

Depending on the way that the fabrics are attached, the structure of the seam varies. And so the steps to make them, and their properties (see Types of Seams).

Some of the most common seams are French Seam, Welt Seam, and Fold Hem, to name a few.
