I am opening a wellness studio and have been so puzzled on what to do for flooring. I have titles in the area which is so cold! I don't want to replace with wood (already using bamboo on yoga room) because of cost. So I bumped into this and love it! I found tatame mats sold in 3x3 or kits. My room is 12x17 so I would have a couple of feet without mats. These look nicer and longer! Where did you purchase them? Thanks!
