i THINK if you put paper down (brown paper maybe) and use a warm iron on it, it should soften up and stick to the paper and come out. we have to do it on the carpet (our three wick got burned a little tooooo long and spilt on the carpet... lucky it's crummy old carpet

FWIW - get a snufter for your candles - if you blow them out, you get wick drift which causes them to burn unevenly (or through the side wall as happened to us - hubby has now learned he MUST use the snufter!).
