machine quilting?
assuming so-
it depends on the quilting- if you are stopping, and restarting somewhere else- you need to cut your threads, and start again somewhere else- i don't (tie off) i bring the bobbin thread to the top at the beginning- take 2-3 stitches in place, start quilting- when i pause somewhere i clip the threads -
when i have to stop somewhere i again bring the bobbin thread to the top take a few small stitches and clip the threads-
i try to do (continuous line) quilting as much as possible...meaning i don't stop and start unless i absolutely have to
