I got the Martelli mat and rotary cutter and ruler at the Knoxville show last summer. Before, I could only cut one or two fabrics (carpal tunnel) but now I can do the whole quilt at once. This is the best system I've ever used. The ergonomic design of the cutter makes cutting feel natural. Plan on getting another in Paducah, just for a stand-by, just in case. I don't ever want to be without it.
