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.
A lego wall. Add this to my fun wall ideas. So one wall will have chalkboard paint, another dry erase, now a lego wall. Now I just need a felt wall for felt play and a magnetic wall. I saw this neat project somewhere about a ball track on a magnet wall.
Life size Lincoln Logs made out of pool noodles~ 15 pool noodles from the dollar store, cut in half, cut notches out easily, with scissors = hours and hours of fun playtime! These were my favorite toy as a kid, love the life size!
