I am a huge fan of Creative Grids rulers. I have them in everything and size that I use. The clear and black lettering helps me see much better, no issues of cutting wrong lines or sizes. The grippers on the bottom are a huge help. The green and yellow gridded rulers caused issues for me, couldn't see as well. I love the 3.5"x 24.5". I only wish they made a 2.5"x 24.5", instead of the 2.5"x 36" one, which is great for cutting fleece. Ebay has great buys on the rulers, several businesses offer free shipping.
