Have you ever cut through your cutting mat?
I have! When I trim a quilt prior to binding I always lay it out on the bedroom floor and slide my large Olfa cutting mat underneath and trim like that. Well, I did that yesterday and just as I got started trimming I heard kind of a cracking sound and found I'd cut all the way through the mat! Horrors! The cut through/ cracked portion is only about two inches in a cross or plus shape and close to a corner so my mat is still useable. Now I'm wondering if pressing on the mat with my cutter on the carpeted floor (it's nubby berber) rather than a really solid surface caused it to crack. Do cutting mats get brittle?
