Bobbin thread?
I recently heard that using poly bobbin thread is not the best idea when making quilts with cotton fabric. Can someone tell me if I can use regular cotton thread in my bobbin or do I need to find actual cotton bobbin thread. Is there a weight difference? I ran out of bobbin thread (was using poly) but now I'm not sure what to use. I can't find cotton bobbin thread on the spool at my local shops. Just prewound. Thank you.
