I would love a rug for my library, a CHEAP one...I don't really care what it looks like as long as it's not cutsie and bright (not my style.) My school is really strict about the rugs being flame retardant. We have to clip the tag that says it's flame retardant, then a photocopy must be made for our room (the office keeps the original tag.) I keep seeing great rugs around at places like WalMart and Target, but none of the rugs say 'flame retardant' on the tag. Am I missing something? Are only the really expensive ones truly flame retardant, like the ones from Lakeshore??
