I got a Cricut machine for my birthday (July). I had an old one for years, but...I got the new fancy gal....and I've been going to town. The one draw back are those expensive sticky mats. I was told by a fellow crafter that you could 'restore' the sticky to a board. Whatever. But WAIT! I gave it a try with my mat. It had little pieces of glitter from some glitter cardstock, and all sorts of pieces of past projects. I had to tape down my papers and it still moved a lot.
I was told to take one of the counter wipes (like chlorox, but....they aren't picky, I've tried out different kinds just b/c I've used what's on hand).
Guess what? It totally worked? I just scrubbed until there was no bits and pieces. I had to wait until it dried (a few minutes) and it was so sticky I can hold it up. I've been using it ever since. IN fact, it's the perfect amount of sticky b/c when you first use these things somethings it's hard to get your paper off in one piece. I don't know how many times I can restore it, but....this one mat has lasted for over 6 months and it's still going. Even one time is worth it, but....I'll just keep going.
