Hopefully everything will go well with yours! I've learned that thread type and needle size are important. What works on a practice sandwich won't necessarily work on a larger quilt. My 100% cotton thread was breaking, so I switched to an all purpose thread. I was getting thread bunching on the bottom, I switched to a larger needle. The regular machine quilting needle couldn't get over the thick seams where several blocks were joined. Just tried to do some more quilting yesterday, and thread keeps breaking. Guess I should have kept going the other day when I was having success! 80% done, I'll get there eventually.
