Guide :Sewing Machines : Designer I
Designer One "broken thread"
Can't figure out why the machine stops, giving me the message that the upper thread is broken. It isn't broken, nor misfed. I did discover that many times it was because the upper spool of thread was too free spinning. Using the spool holder more firmly helped. However, after sewing for several hours without problem last night, today I can't sew more than a couple inches without getting the thread broken message, same stitch, thread and fabric. This has been on-going, despite being at the shop twice. Help!
