CRH, yes, the white mats are horrible for dulling blades quickly! :evil: One of our local quilt shops used to use one and we all learned to avoid using it because of that problem.
I find I end up buying a mat every few years, though I like the idea of buying one every year for my birthday.
You ladies have come up with some great ideas on recycling old mats. I've got one that would be perfect for when my grandson (due in a few weeks) is old enough to start drawing, painting, et cetera. The other one that I have, I am still using the back but the front is shot. When my mat dies I turn them over and get new life from them. (Remember, you're not supposed to measure using your mat so the plain back works just fine for cutting.) I do have projects that require glueing and using the beat up side of the mat for that is an excellent idea!
I just love all the different tips and ideas I pick up from you ladies!
