I have been noticing that every time I sew a hem, it turns out wavy on one side. I first noticed it while I was hemming jeans. Then I noticed that it turns out that way no matter what kind of fabric I am sewing. It is the bobbin thread that is turning out wavy. I usually sew hems with the pant leg inside out. So the stitching looks good on the side I'm working on (the inside), but the other side is wavy. I've adjusted tension, gotten new needles and thread, but nothing seems to help. Does anyone know what to do able this?

The bobbin tension is too loose. In most cases you can adjust it by tightening the top tension. If properly adjusted, the two stitches will meet dead center of the stitch between the fabric layers. Tighten your top tension and, using a cheap or old cotton thread, regular sewing weight, stitch a few inches. When you finish, pop the sewm...may work better with a knit. If one side breaks more than the other, the tension is tighter on that side. If they seem to break about the same, the tension is balanced. (This is a wonderful way to use up some of that old thread your mom had.)

Pam - thank you for that tip on checking tension. I'll be sure to keep it in mind :smile:
