Step 3: Fuse the layers of chip bags
Fuse the bags by ironing. Lay (no pun intended) the potato chip bag on the ironing board and COVER it with the non-sticky Contact LINER (or wax paper). Set your iron on “wool” setting. IRON the non-sticky Contact liner, with the bag underneath, back and forth, around and around slowly. (Be sure your iron does not directly contact (no pun....oh, nevermind) the chip bag or it will stick to your iron!)
Occasionally lift up liner and check to see if the 2 bag layers are fused completely – the layers should not be separable. There will be wrinkles, but that is part of the charm. Fuse the 2 small chip bags separately the same way.
