Why not just replace the floor with wool? Only way I could see this being practical is if you were on a 2nd floor carpet and didnt want the wool to be seen from the 1st floor.
Yes it does seem like a good idea, but only 1 problem. You prob couldn't put anything on it ex: crafting table, chest, furnace. Other than that I LIKE IT.
Three Wools of any colour make 3 carpet slabs o red, also can be dyed
Includes wallpapers too o.o
