I changed out my mats to Quilter's Select brand. Light gray on one side and dark gray on the other side. I also bought QS rulers in the basic sizes. They are the best I have used. I buy Creative Grids rulers when I want a speciality ruler. The rulers that have the colored lines like yellow and orange were always on the guild free table. No one wanted them. I have a few left of the bigger size squares I use for square up.
