This reusable, double sided, multipurpose craft sheet is made from ultra high temperature glass coated with non-stick Polylon. For fusing appliques, place pattern under sheet, arrange all the overlapping pieces on top and iron. Entire design can be gently peeled off. Use as a pressing cloth over any surface an iron should not directly touch. Great for ultra suede, lame', felt, iron-on metal designs, paper piecing, photo transfer paper, painted wood and heat setting paint. Promotes even heat and keeps colors from bleeding together. Makes an easy to clean up work surface for hot glue guns, glue melts, wax designs, fabric stiffener, rubber stamps, glitter, kids projects and more. Mix paint on it without it absorbing in or buckling. Bake shrink-art, clay projects, salt dough and ornaments without damaging the sheet. Measures 13"x17".
