I have the 24 x 36 Quilter's Select mat on top of a Sullivan's 33 x 58 mat and a smaller mat on top of those. I don't need the big mat that much so use the smaller mats on top of it. I also have the Martelli Roundabout on one end of the table. I have Fiskars, Joanns, Olfa, Polar, and Omnigrid mats of all sizes. I really like he Omnigrid because it has no grid lines. It has the Fons and Porter's brand on it.
