Candles in cages

I noticed a great idea (both practical and beautiful - hurrah!) in this month's Homes and Gardens. One living room had been styled with enormous church candles inside a wrought iron birdcage that had been placed next to the fireplace. What a great idea - the candles looked pretty and whoever owned the house could be secure in the knowledge that they wouldn't get knocked over or spill wax all over the place (a BIG concern when it took you a whole weekend to treat, sand and varnish the floor!). Any advice on where to pick up 3ft candles for very little money would be greatly appreciated! (Image via Credit Crunch Bride)
