Zig Zag Stitch is best described as which property?

• A. Links interlock at the corner of each stitch; stitches should lie flat
• B. It forms a decorative pattern
• C. It uses only straight stitches
• D. It cannot be used on woven fabrics

Answer: (A)

The zigzag stitch is defined by the needle moving from side to side, creating a zigzag path that lets the thread wrap around fabric edges and interlock at the turning points of each stitch. This interlocking at the corners and the way the thread stitches across the edge helps the seam lie flat on the fabric when tension and width are set correctly. That flat, flexible finish is why this stitch is so versatile: it finishes edges to prevent fraying, accommodates stretch, and can be used on woven fabrics without puckering. It’s not limited to decorative use, nor is it restricted to straight stitches, and it can be used on woven fabrics.
