What is a "seam"?

A seam refers to the line of stitching where two or more pieces of fabric are joined together. Seams can be created in various ways, such as through machine stitching, hand sewing, or through the use of special tapes or adhesives. Seams can also be reinforced with additional stitching or bindings to prevent them from coming apart. In addition to their practical function of holding fabric pieces together, seams can also be decorative elements in clothing design, with various seam types such as French seams, flat-felled seams, and mock flat-felled seams.
