This year has been a big home improvement year, and summer vacation was no different!
Over the 4th of July week I built a dog run (with about 4" of pea gravel at the base):
And we converted the boys' Train theme (complete with working train set around the top of the room) to a NASA theme.
We did have to buy the 4'x6' Shuttle for one wall, but the rest came out of my Lego/NASA/space collection and existing posters that the boys had. I did make the face for the clock on the wall, too, reusing the train clock they previously had. We also plan to get a futuristic bullet train to use with the existing track.
