We are currently out of our grip tape due to a supply shortage. In the meantime you may search for "3m TB731" online and there are some other vendors that my have it. Sorry for the inconvenience.
1" wide grip tape is used for helping to hug the tool to the cloth. This tape is made out of a silicone material and will not damage your quilt. Not suggested for the AppliGuide or AppliRuler where you will want the tool to slide.
