I took several manila file folders and made a frame on each one with an opening that was 3/4" smaller than the square to be signed. This gave me an 3/8" space on each side and top and bottom. I glued a piece of fine-grit sandpaper where the opening was and wrote out the instructions for positioning the fabric to be signed inside the square. Also, I asked someone who understood and could explain the procedure to other guests to sit at a table and make sure everyone did what they were supposed to do. I did it this way, because I don't have a lot of luck getting freezer paper to stick to fabric. I read and re-read instructions, but I'm either getting the iron too hot or not hot enough, heating the paper / heating the fabric / not heating the paper enough / not heating the fabric enough. For me, sandpaper and a frame was the best solution, and I have a supply of them that I can use forever.
