You’re dealing with correcting uneven thread tension when your stitches look wonky or your fabric puckers like a bad hair day.
First, check that your thread’s properly seated in the tension disks and bobbin case—it’s like making sure your shoelaces are tied right.
Next, adjust your tension dial gradually, testing on scrap fabric as you go.
If your upper thread’s showing on the bottom or vice versa, you’ll need to balance both upper and bobbin tension until they lock together neatly in the fabric’s center.
Sometimes the culprit isn’t tension at all—worn needles or poor-quality thread can masquerade as tension troubles.
