The carpet tiles are the way to go! If you can't find some to purchase from a player, there is a quest you can do to get them. Go to the tailor shop in Ter Mur, the town closest to the moongate. Get the quest from one of the tailors, follow instructions and when it is complete, various types of carpet tiles, corners and edges will be available for you to purchase from the NPC there. They are a little costly, but not as costly as a little dinky rug! lol
