Zig Zag Stitch8:27 PM
Zig Zag Stitch: a stitch that creates a Zig Zag pattern. Zig Zag stitching is used for finishing seam edges, stitching seams on stretch-knit fabrics, and decorative top stitching.
The picture below demonstrates the finishing of a seam with a zig zag stitch. The stitching is right along the edge of the fabric, so the stitching catches the edge and keeps the fabric from fraying.
