I love my martelli cutting mats. They are nice and thick. I have a 24 x 36 (I think that's the size) and a rotating mat. I also love the 45 mm rotary cutter but don't use the 60 mm very much. The blade skips after less than one project. I looked at some of the rulers but I think they're black? Seeing my fabric behind the ruler is important for the way I cut.
