Lighter coats may make it curl less. You can try a heat gun or heavy book (when it's dry) to flatten it. I have a craft iron I use sometimes. Overall though, you're going to get some of that crinkling/curling because you are putting a liquid on your paper. I love Glimmer Mist so I don't mind all that much.
@Michelle..yep, I sprayed it VERY lightly. I think the ones I have are Tattered Angels mists. I think something w/more color would require less spraying. I had gotten the idea of maybe getting a spray bottle and putting some acrylic paint in there w/a bit of water and seeing what kind of effect I'd get w/that. I did put something heavy on top of my paper afterwards and it helped a bit w/the wrinkling. I have seen alot of ppl use mists and I just LOVE the way it looks, but I had the crinking of the paper part Thanks for the help
