So I'm trying to practice my FMQ, and it's pretty ugly, but tonight something happened that I can't explain. I've just figured out how to bring up the bobbin thread. I'm working on these silly potholders I made to give to family. So I bring up the bobbin thread and work on a nice spiral design, but when I look at the back, it's all thread nests and horrible! What did I do wrong? I thought that if the bobbin thread was up that wasn't supposed to happen! I've thrown away about half a spool of thread - it happened twice! I'm going to bed now but I hope in the morning you will all tell me what I'm doing wrong.
