Sorry, this response is a bit late. I use the Cricut to cut fabric all the time. In fact, ever since I discovered I could, I'm fairly certain I may have cut more fabric stuff than paper. Anyway, what I do is purchase Wonder-Under or Heat & Bond (Heat & Bond is a bit more expense, but has more of a hold when you are ironing it onto something). Then I take it and put it paper side down onto my Cricut mat and cut it at the highest blade depth and I believe third down from the fastest speed (I think it's medium?). The mat needs to sort of be just the right stickiness. If it's too sticky it makes things difficult to remove, but if it's lost a lot of its stickiness it will come loose while you're cutting. If it's not brand new, but not really old and used up, it should work just fine and it looks great for things like letters especially. Let me know if you have any questions.
