I have the big huge white cutting mat also. My husband bought it for me for my birthday this past year. It covers my entire table that we specifically bought for my sewing table. The only problem I have with it, is that it moves around on me. But I did see on here where Grama Lehr says she uses some spongy shelf stuff under hers to keep it from moving. I am going to have to get some. Because I wouldn't trade this cutting mat in for a million dollars. I do have a purple cutting mat thats huge and I do need a smaller one to take to my sewing class with me. :) As for the ruler, I have one of those lipped rulers that I use mainly when I cut on my white cutting board, as the lip is JUST the right depth.
