Tired of your spools tangling and unraveling and making a mess? Wrapping a Wonder Guard™ snugly around your spool holds the end in without tying or clipping and stops it from unwinding and tangling. Wonder Guards, sold per pack of 10, also keep your threads clean and prevents them from drying out. This multi-purpose thread guard can also be attached loosely around spools of thread while in use on a machine for a consistent draw, helping to maintain beautifully even stitches with no fuss. This size is especially made for larger sized spools of Decobob, InvisaFil, Spagetti, Tutti, Fruitti and more.
