We had some leftover siding from our house that we put up on the playhouse. Unfortunately we only had enough to do the front. But we wouldn't need to get much to finish it off. But that's still undecided right now. Darcy brought home some free fascia wood (for the trim around the window) and I painted it with leftover house paint so today's efforts were free!
I also painted the door and we had a leftover doorknob, too.
Somehow the dog managed to get paint on him, too. He's got a bit on his snout and his back by the tail and I think there's a bit on his other side, too. How he managed to do this, I do not know. But it will wear off. Sooner or later.
