I got this idea HERE. I saw it, liked it, and made my own.
This is the birdhouse before I sanded it.
I glued a candlestick to a base then to the bottom of the birdhouse and let it dry.
Since I was going for a particular look, I painted the tower red.
Then spray painted it yellow. After it dried, I sanded it, so the red would show through. Lastly, display it and enjoy it!
