I have a challenge. When I have a large spool of thread on my sewing machine, as the spool moves in a circle, extra lengths of thread fall out or off the spool, ending up wound around the bottom of the spool and messing things up. When I bought my sewing machine, the dealer gave me some tubular netting that fits around the spool and keeps this from happening. However, he did not give me much of this. I am looking for the same thing or a substitute. All ideas welcomed. Thanks. Kathy
