I have a stretch crushed velvet that I'm trying to sew. I have a size 11 ball point needle (this also happened with a size 14) I'm using and I have one of two things happen EVERY time. It sews for a minute and either gets stuck in with the bottom thread or the top thread breaks.
I've tried adjusting the tension, but it doesn't seem like a tension problem. With that, it is usually only on one side. This doesn't seem to have any rhyme or reason for whether it will catch on the top or the bottom.
WTF? I just don't get why it is happening. Any ideas for things I could try?
