Just draw, cut and bake--that's all you'll have to do with Grafix Shrink Films. Apply the design to the sheet (draw, trace, or rubber stamp), color it, cut it out and bake it in the oven for a clean, colorful, fun new personalized craft project! Great for creating one-of-a-kind jewelry, miniatures, ornaments, greeting cards, bookmarks, tag art or package tie-ons, key chains, and more! Ideal for kids (with adult supervision), teens, and adults. Test colors for permanency on a scrap piece of film first, try water based acrylic paints, pencils/pens, ink or heat set paints. Roughing up the surface by sanding (280 to 320 grit) helps to adhere the color to the shrink film when rubber stamping or for designs that will be washed or used often. Packs of 10, 8 1/2 in. x 11 in. sheets.
