I'm kind of new at quilting, so this may be a question or problem I should be able to resolve, but I'm stuck. I'm using a babylock katherine with a walking foot. THings were rolling along just fine until the wallking foot eventually jiggled itself loose and I wasn't even aware that it was. Then it went on to a broken needle because I didn't have the needle positioned correctly. Then the thread started breaking. I started a new spool of thread, made sure I threaded the machine correctly, got the walking foot on correctly, put in a new needle, and reset the needle position. Now, it goes maybe 10 stitches and then skips a huge amount (maybe 10 stitches worth) stitches a couple good ones, then skips again. I don't know what to do.
