Want to use larger spools or cones of thread on your home sewing machine, but the spool pin on your machine won't accommodate such spools? The Thread Stem is the simple, cost-effective solution. For years there have been thread stands, but they take up additional table space, are not portable for travel. The Thread Stem Tool enables you to use large spools on your sewing machine. It is less expensive, takes less space & is more portable than thread stands. It is fast & simple to use, no assembly required. Works on virtually all sewing & embroidery machines.
