Hi "Joe's Mom". I am also a "Joe's Mom" And coincidentally, my "Joe" lives in Ballwin, Mo! So we have a "connection". Thanks for the info on the mat. I've tried several and I think I'm just going to have to use the grippy dots on my ruler. I'm thinking of starting a new quilt and wanted to make sure all my cuts were more accurate this time. Have a great day! -- Phyllis
