Double-Sided Permanent Adhesive Sheet

This is a "dry" or peel-n-stick adhesive, so it won't squish out edges or get where you don't want it to be.  We use this adhesive to stick Little Windows onto things, and to each other. Simply trace the shape you want, cut it out, peel one side of the backing off, press onto item, then peel off the other side of backing paper and stick it to your surface. Strong, lasting bond. 4 x 4' sheets sold individually.
