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. The Thread Stem is simple to use (no assembly required!): just insert it onto your machine's spool pin (see pictures at left) and put your thread through the hole at the other end. It works on virtually all sewing and embroidery machines and its highly visible red color means you won't lose it! Dimensions: 8" x 1/2"
