Pooks- did you get it fixed?

I would really focus on the bobbin thread. What kind of machine are you using? I have a Janome and it is very fussy about the bobbin being threaded correctly. Are you using a walking foot for stitching in the ditch? If not, that might also be why you are having trouble. Hope someone here can help you solve your problem.

I suggest that your problem has something to do with tension. Remove the bobbin, put it back in, making sure that the thread goes through all the places it is supposed to go. Then for good measure I would re-thread my machine. One of the ways to avoid this problem is to have a "leader", a small remnant of fabric that you sew onto when you are finishing piecing and then something you sew from to begin piecing again. This leader will also save some thread by not wasting it by ending your stitching, pulling the thread out and then cutting. I hope that is making sense.

Hi and welcome from Alaska.

I never heard of pulling the bobbin thread to the top of the quilt. Is this only for quilting or for all sewing/piecing? What does this accomplish in the sewing process?

Have you lowered your presser foot?

Yes rethread your machine, and make sure your needle is up all the way when you do.

I wonder if the feed dogs are up?
