Color-Your-Own Stained Glass Window Clings allow you to create beautiful stained glass in the colors you choose to beautify any window. Decorate the clings with markers, glass, or glitter stain for instant transparent beauty. Static cling will hold them to any clean window (or even mirror) but they can be repositioned or moved easily and without leaving sticky residue. The black outlines are raised for easy coloring. Leave them uncolored for a leaded glass look. 24 total per pack (6 each of 4 designs). Each one-piece design measures approx. 8" x 10-3/4". Made of PVC plastic.
