There is a new ruler by Quilters Select, that is supposed to be fabulous. I don't have one yet, but that is what I'm going to try the next time I need to replace my rulers. They don't have an 8 x 24 but do have a 6 x 24, and a few other sizes. The numbers read left to right and right to left, so it doesn't matter which way you use the ruler or if you are right or left handed. They are frosted, so it is easy to see on fabric, and they have a non slip coating over the entire ruler, not just in "spots" like the Creative Grids. They are supposed to be coming out with more sizes in the future also.
