I'm starting a project that uses Angelina Fibers, and I haven't used them before. I've watched a couple of tutorials, but I wondered if any of you have any tips about using them. Also, I don't want to buy a pressing cover. Have you used parchment paper with these, and did it work okay? I'm just trying to learn from your mistakes so I don't have to make them myself. And your successes would be welcome too!
