Somewhere here I remember someone mentioning something you can buy at Home Depot/Lowes and use it to rotary cut on and iron on as well... granted I won't use it for cutting but now that it's on my mind of course I can't find the post....
I remember thinking it was in a discussion about the Martelli cutting mats (which I have to say I'm still in love with but didn't get while at the quilt show today)
It is going to drive me nuts! I was thinking about it today and now I can't seem to get it out of my mind and it's frustrating me that I can't remember what the stuff was called that you can get.
