Cause. Tension pucker is caused while sewing with too much tension, thereby causing a stretch in the thread. After sewing, the thread relaxes. As it attempts to recover its original length, it gathers up the seam, causing the pucker, which cannot be immediately seen; and may be noticeable at a later stage.
Why is the thread bunching up under my fabric?
A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
How do you fix puckering?
REMEDIES for Puckered Seams

The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing.
Why is my zigzag puckering?
Polyester thread stretches more than cotton. When wound onto a bobbin, the thread accrues additional tension. The sewing machine applies even more tension to the thread during stitching. After a seam is sewn, the thread relaxes, drawing up the fabric and creating puckers.
How do you fix bobbin tension?
To tighten your bobbin tension, turn the tiny screw on the bobbin case a smidgen clockwise. To loosen bobbin tension, turn the screw counterclockwise. A quarter turn or less is a good place to start.
