I have a couple of pressing sheets, but I find I prefer parchment because I can make the pieces long enough to be the whole length of the ironing board so I can iron lots of pieces ( I have a giant Costco box that I also use for cooking), but I also grab freezer paper if it is handy. I learned the hard way that you need to use something on both the bottom and top when you are using the fusibles -- it is a pain to clean the iron.
