The yellow rulers seem "busy", and I have a hard time reading them. I just bought a 6" X 24' to replace a very old 6 1/2" by 24" that had a few chunks out of it. I really liked the 6 1/2" width because it makes it easy to cut 6" finished blocks. I am glad someone commented on the frosted ones because I was thinking I might like to try one of them next time I buy a ruler.
