I wood-burned a wooden "house" I'd gotten at Hobby Lobby. This was my first attempt (ever!) at wood-burning and it really made a cool "rustic" looking house. I then oiled the wood to keep the natural, rustic look while keeping it from drying out in this Colorado desert!
The 1" cubes I'd gotten were too small for the openings, so I put 1-3/4" flat squares on the cubes -- we then did the symbols and name of each antiphon -- Sapientia, Adonia, Radix Jesse, Clavis David, Oriens, Rex Gentium, Emmanuel and I added a final one for the 24th -- Light of the World. Just used Sharpies and a bit of patience.
I think the final result will definitely be a family tradition for years to come!
