Quick Answer: How do you end a straight stitch?

Why is my straight stitch zig zag?

If the upper thread appears as a single line, the lower thread is incorrectly threaded. Instead of the appropriate tension being applied to the lower thread, it is pulled through the fabric when the upper thread is pulled up.

Why does my top stitch look wrong?

Poor thread tension on a machine-sewn seam can result in an unstable seam, puckering, or just plain unattractive stitching. Perfect machine stitches interlock smoothly and look the same on both sides of the fabric. If you see small loops on the right or wrong side, the thread tension isn’t correct.
