Candle wax on tablecloth

I have had candle wax drip on just about every tablecloth in the house.  I used to freak out about it, but heard you could get it out.  The process?  Scrape off as much as possible and then put tablecloth face down over the sink and pour boiling water through it.  It melts the wax and it drips away.  I've used this method over the years and it works great.  Enjoy the candles ... just be sure to never leave them burning when you leave a room.
