For those of you who have done this, is there anything special I should know before I give it a try? I got the glue stuff in my stocking (Santa may have been given a hint about that one ;)) and I'm excited to try it since both of my mats are barely sticky at all anymore. I read on somebody's blog that you need to really let it dry well (like 24 hours or something?) or it will be too sticky. Anything else I need to know?
