Two talented ladies on Bainbridge Island, WA designed a process to make floor mats. Here is the site as well as information on the kits. I have seen these mats in different sizes and in quite a few shops around the area...eventually I will make one for myself! They are not difficult to make. You could even use a solid piece of fabric you like or make blocks or a mini quilt for the actual mat.
