I love my little 4.5, especially when paired with my small rotating cutting mat! A few years ago, l purchased 3 creative grids rulers in a set sold by Joann's. Included was the 4.5". 10.5 " and 12.5" . I've since lost the 10.5" in a move 😒. The 2 remaining are used constantly. I don't use grips, instead l have my cutting table set not too high, so l can easily apply some downward pressure. When trimming sewn blocks, l find doing one at a time the most accurate method.
