Handy Nets are made from loosely-knit netting and are placed over cones to prevent thread from sliding down the cone. Wrap a net around the cone of thread while in use. Leave net in place when storing thread to prevent unwinding. Recommended for smooth and delicate threads such as metallics, trilobal polyesters, MonoPoly, and other threads. Superior length Thread Nets, long enough to double back over themselves for added control of the thread when using cones for both the sewing machine or the overlocker.We buy these in bulk, so you may name the quantity you'd like.Each Thread Net is 6" long
