My first few were prepared by the local T shirt shop. They feel kinds like plastic. Then I bought the wrong type of printer-prepared fabric. (There are really good ones, the first one I got is not permanent!!!) Now I use BubbleJet and prepare my own. It takes a little longer, but because I supply it, the fabric is top quality. I iron a 9x11.5" piece of fabric to the same size of freezer paper then trim to 8.5x11. This works for me.
