Today, I went to a local chain of craft stores called "Pat Catans" because I was looking for poseable wooden hands in their art department. When I went past the drafting section, there were cutting mats. I got a clear 24x36" mat for $23.00. Actually, it is even thicker than a "quilting" rotary mat. The biggest difference is that it has a half inch grid, instead of a 1" grid. I rarely use the gridlines on a cutting mat and for the difference in price, even if I did use them, I would re-learn.
What I really need is to bring some more cabinets and things upstairs so I will have a place to put some of the things that are cluttering my table top!!
