Have you ever noticed that when you get a new mat, it's really sticky! I mean, REALLY sticky! In fact, it's best to only use heavy cardstock initially as the mat will not let the thinner paper come up.
To combat this, after opening the mats up, I usually press the mat against a clean T-shirt (or the one I'm wearing, ha ha!) and this removes the excessive stickiness.
But, Cricut Dan has an even more interesting idea and people on the yahoo group say this prevents those little paper stickies from clinging to your mat!
Look HERE to see Cricut Dan's video about this!
