Thread nets are a great way to tame slippery specialty threads. Slip a thread net over embroidery and serger threads, the net keeps the thread from slipping to the bottom of the spool and getting caught around the spool pin. A thread net also keeps wiry metallic threads from twisting and kinking as they come off the spool. Thread nets can be cut in half for smaller spools or double them over to use on any size spool. Each net measures about 6" long and fits any size spool. Package of twelve.
