That's EXACTLY why I hand piece and hand quilt! Machines tend to instinctly know that I'm not good at fixing things. A machine can work just fine, but when I sit down the machine seems to say to itself "Aha, here is a good one for me!" Then it either jams, runs out of bobbin thread, bunches up under the material or does something else really "wonky". So, I just stick to a needle and thread! Much less frustrating for me!
