What size of placemat do you prefer, I was thinking 15" x 19", maybe 14" x 17"?? What would you put in the center, warm and natural or flannel? Does anyone have a nice pattern or know where I can find one? It will be for a batchelor and have farmall tractors on it. I have 3 fabrics: Green with International H; Tan with black farmers driving a farmall, plowing, combining, etc; the third is red with black. Any ideas will be appreciated. Thanks
