Wow ! Thanks for all the input on cutting mats. Several brands I had not even heard of but am going to do a little research on the Martelli. My mat is shot but I guess I COULD turn it over and get another 20 plus years out of it. lol ! but I DO use the lines for cutting. sooo. The other thing I could do is just start cutting in a different spot. Lots of options... I just wanted to thank all of you who chimed in to help me... got lots of good advice (as usual) ! you guys are the BEST......
