I'm trying out a new product line: Birdhouses! I collect them myself so I'm naturally interested in creating them, too. I buy the houses in plain wood then paint and paper them. They will all be sealed, just like everything else I do, but I don't know if you can actually leave these outside. The ones I collect are decorative and always inside my house, tucked into bookcases or next to candles and vases. Let me know what you think, I'd love some feedback!
