I used my Shape Cutter for a lot of 2 1/2" strips last night. I dscovered one more thing to be aware of. The horizonital lines are very thick, so the edge could be crooked under the line and I wouldn't know it. I made sure I could see a space first, then backed the fabric up just to the edge of the line. I shook my fabric straight, pressed it at 22", folded it again without pressing and put it on the table. I then lined the folded edge up with the EDGE of the black line, cut at zero to straighten and cut at 2 1/2" and 5". I did have to hold the ruler firmly for two reasons. 1)I don't have any Invisigrip on it yet and 2)with the slots cut in it, it's not as stable as a regular ruler. I had no wonky strips. Happy cutting.
