I'm a new quilter - now quilting a sandwich which will be my first [finished] quilt for charity for our guild.
Don't laugh but the tough part for me is thread-handling - knotting & burying my threads.
Yesterday I realized that the last 3 feet of stitching was no stitching at all --- ran out of bobbin thread. Turned the back over and found more than a few threads that needed treatment, so I walked out of my sewing room. It was such an automatic reaction haha.
I decided to take up the challenge today which I did and now I am ready to proceed with the rest of the quilting.
So: thread problems - that's where I go off the rails.
