stitch witchery

Try a little "Goof Off". Try on an inconspicuous spot top be sure it will not damage the fabric first.

Heat your iron to cotton, or as hot as the material will allow. Take clean piece of white terry towel and place over the area, apply the iron for ten seconds, then lift. The residue should come up onto the cloth. Move the cloth to a clean section and repeat until all or as much of the stitch witchery is removed.

Stitch Witchery is designed to be a permanent thermoplastic bond, so you may be able to remove all the residue via the heat method. You can try the other poster's response of using "Goo-Gone" or another solvent, but make sure to test on a small hidden area of the fabric first.
