Thanks so much everyone! I knew this would be the place to go to for help! My quilting board world is so full of great people I knew I would get the help I needed! I had cleaned and oiled the bobbin case but went back again after all the suggestions and did the deep cleaning I would normally do after finishing a project and before starting another. Also, I have a feeling I may have left the presser foot up when rethreading, that hoping foot does look the same up or down polyparrot. Anyway, after trying the suggestions you wonderful quilters suggested I think I have it working now. I was left with one tiny tiny loop in my sample line of stitches, but I'm sure that will be worked out on its own! Thanks again to all you wonderful quilters! Love this board and love love love all of you!! So grateful to have stumbled across this board!
