Why does this happen? And it happens a lot. Right when I start to sew, the machine gobbles up the thread (it's the top thread pictured there on the bottom side). Sometimes it's so bad it gets all wound up in the bobbin case and I have to open that up and pull it out. It does not matter what thread I'm using, what type of needle I'm using, or the fabric. In this case I was sewing two pieces of knit cotton together with the appropriate needle. I also had my machine serviced recently. If I start with the needle up, needle down, new needle, old needle, in the fabric a bit, at the edge of the fabric, it's all the same and it's driving me nuts.
Is there a Car Talk for sewing machines?
