I bought a single suction one for 1.99 at threadart.com. Same concept. I didn't buy the other one since I wasn't sure if I could work with it. But its great.
Yesterday, I went to Joann's and purchased the Invisigrip, it's a non-slip material that is applied to rulers, cutting mats, and templates to prevent slipping when rotary cutting. It's 12 1/2 inches x 1 yard. Just thought I would add my 2 cents. :lol: :lol:
