When I first started applique I did not know about the parchment paper. Ended up purchasing two applique pressing sheets - expensive. Then heard about parchment paper and gave it a try. I absolutely love parchment paper. No adhesive sticks to it but I found the pressing sheets had to be checked quite often because adhesive residue would cling to them and then adhere to the top of your next project if you happened to reverse the the pressing sheet. I would continually run a shower scrungie over the sheet after every use. I have never had this problem with the parchment paper.
