Muse&Sew

No fun Lstew2212. I'm not very good as a sewing mechanic, but like moonrise says, redo the upper thread. Usually I've found that there is a thread stuck somewhere, or junk has collected in the bobbin or upper thread area. When my machine gets a little out of whack, I take out the bobbin & clean that area. i love to use canned air too. I sew with a lot of minky & so my machine fills up with extra threads. So I have to clean the bobbin area frequently & spray the canned air. Depending on your machine, some machines allow you to unscrew the top area & look for threads that are stuck. Once you clean out the junk, rethread, etc. it might work. Good luck!
