Snarly messes of top thread. Ugh.
|I got stubborn and kept stitching here and it went back to good stitches!|
I have this issue every once in a while. Still haven't solved it. Can't get the machine to do it when I take it to the dealer (had the same issue on my old machine too) and my hubby who is pretty knowledgeable when it comes to sewing machines can't quite figure it out either.
|Can you see the loop of top thread going around the bobbin thread?|
I have two theories:
- The needle is piercing the 'working' thread as the stitch is being formed. The working thread is the length of thread that is pulled around the bobbin case with each thread. Any one point on the thread gets pulled down into the bobbin case many times before finally laid down as a stitch. I try to avoid this by not stitching directly backward (pulling quilt towards myself). But this usually results in broken thread.
- The plies of top thread for some reason are coming apart and the hook is grabbing only part of the thread to form a stitch. I used to think this was only with a thick thread and maybe my hook was damaged or just a tiny bit out of time. But, no damage, and this issue comes and goes with no rhyme or reason and with different threads.
After shooting the video, I turned my machine off and did something else for an hour or so. When I started stitching again, there was absolutely no issues. Go figure.
Using quality polyester thread- a little slippery, maybe a thread net would help. I even spooled off several meters in case the thread was defective. Threaded properly, tension good in between episodes, and I'm experienced enough to not have issues to to jerky hands. Good needle, etc.
Just goes to show that even when you're an experienced quilter, things still go wrong now and then. So if you are just starting, don't give up when having trouble. Change a setting, thread, needle, tension, foot height, etc. and see if that helps. But sometimes this free motion quilting is just so different from the sewing that these machines were designed to do, that you might have occasional mystery issues.
