To cut the holes in the top, I used a drill with a keyhole drill bit. That only cut a ring around the center about 1 inch deep, but, left the wood in the center. I used a wood chisel to chip out the excess wood, which again took longer than I had thought.
Now for the easy part, I painted two of them with solid color paint, that I just poured out of the can and let drip over. The square one, I painted with a brush, using red paint, then brushing white paint lightly over it. I then melted candle wax and poured over the top and allowed it to drip down all sides.
Last I inserted battery tea lights. Chipping out the center was what took the longest time. If you have a drillpress, and a cut off saw, it would only take minutes to do all of it.
Hope You Have a Blessed Day,
