Zig Zag Stitch

Zig Zag Stitch is widely used in sail making because it spreads stress across the fabric, preventing tears and keeping sails strong under heavy wind loads.

It also allows the material to flex slightly, which helps sails last longer in tough marine conditions.

Sailor’s note: The zig zag stitch isn’t only for sails - sailors often used it for repairing canvas covers, hammocks, and even clothing at sea, making it one of the most “nautical” stitches around.
