Brody's Room in Pirate! I could totally do this in our house! Our gallery wall and paneling wraps around to right outside Mason's room, I might just have to slap a few coats of chalkboard paint on there! And maybe some magnetic paint under?
Already have a small lego table but son is outgrowing it. Would love to do this on a bigger size table for him. Would be good for a kid's playroom. If you did velcro to attach it, you could switch out the base plates maybe.
