Made these candles using PVC pipe. Cut your pipe to all different lengths. Roughen with a little sandpaper then paint white. Get yourself some battery operated tealights and measure the height of the tealight without the flame. On the inside of your PVC pipe put little tabs of double sided tape. This will stop your tealight from slipping right into the pipe. Last, but not least, dribble melted wax down the pipe to make it look more authentic.
