1. To make thread behave for appliqué or regular sewing - run your needle and thread through a fresh dryer sheet, folded, and magic - no tangles or those tine little nasty knots.
2. Ever wonder why your quilting thread will tangle and knot up sometimes, but cooperates beautifully other times? It matters which end of the thread you put your knot in. For North American-made thread (i.e.. Coats) put your knot in the end that you cut from the spool. For silk thread or European-made thread (i.e.. Mettler) put your knot in the end that you pulled from the spool. This way, you work with the way the thread was twisted when it was manufactured.
