|While making the ears of a batman costume for my DS, I needed to interface small triangles. I had already cut the small fabric pieces. I cut a generous piece of interfacing, laid it sticky side up on the ironing board, laid my cut triangle on top of that (wrong side down), laid a larger piece of gift wrap tissue paper over that and ironed. The excess interfacing stuck right to the tissue paper. I turned the whole thing over and ironed the other side as well. Then, I cut the whole thing along the lines of my fabric triangles, which I could see easily through the gift wrap tissue. The tissue just fell away and I had a perfect interfaced triangle.
