The Simplicity deluxe rotary cutter stinks. Do not buy it. It is not accurate enough for anything, much less quilting. The first time I used it I thought I was doing ok and wasted 1/2 yard of fabric before I realized spagetti was straighter. Fortunately I bought from nancy's notions and she took it back. Recently got a quiltcut2. While you still need to use a rotary cutter, it's much easier than just using a mat. I saw eleanor burns use something that looked like a quiltcut but the bar had a blade on it. i'd love to find out what that is and get one of those. I've had neck surgery and sewing isn't the best hobby for me. oh well.
