Apply design and background colour Cut out your design with regular or decorative scissors. Punch holes with a paper punch. Holes will shrink too. Bake on medium weight, non-corrugated cardboard ( or sandwiched between two sheets) or on Teflon. Avoid baking on bare metal. Bake in a regular or toaster oven at 300f/ 177c for several minutes or heat with an embossing heat tool.
