That's hot. Our current house is high-contrast like this. I was thinking of going a bit more muted in the new space, but I am still drawn to this look! I probably won't have the three-sides walls, just a corner and probably a shelf as the third wall, then a curtain for a closeable "fourth wall". Or, who knows, we may luck out and get a den!
Star wars planet party game I used this pin for inspiration but instead of a board we used the spongy foam camping mats you can get (the kind with holes in them), and stuck the tails of the balloons through the holes and secured with a peg on the back. Each balloon had the name of a planet inside (written on a laminated disc of paper) as well as a party popper, each planet corresponded to a plastic gift box full of little toys and lollies
