I am not familar with this tool could someone provide a link. My google search was not sucessful.

I used the Double Diamond Ruler from Bright-Quilting-Notions. I used the 3.5 inch ruler instead of the 1.5 inch ruler (they both come in the same package). I bought my rulers at a quilt show.

I bought that cutter at the NJ Quilt Expo and haven't used it yet. That's a great idea to use it - love it.
