I've done raw applique before, but I'm getting ready to do Interfacing Applique on a quilt. The directions say after sewing the interfacing & applique together that you turn it inside out & press flat. And to press using a non-stick applique pressing sheet. What is a non-stick applique pressing sheet? Can you get it at Joann's or Hobby Lobby? Is there anything that I could use that I might already have...parchment paper or something? Thanks for any help. It's very appreciated.
