This Cone Spool Stand adapts overlock thread cones for use on any sewing machine. Place thread cone on spindle, guide thread through the top thread guide loop, and thread machine as normal. The heavy weighted base will keep it in place as you work. It is also used by quilters and freemotion embroiderers for specialty threads like metallic and rayon that might not like to feed through the usual path on their machine.
