My parents had a train table in their basement that my grandfather built for my brother. They didn’t want it anymore so we brought it back to our house. It has a large mountain on it that is not finished. I had the kids work on finishing it with their hands. They were a bit afraid to get dirty at first, but got into it towards the end. While they didn’t finish, they had a fun start. We’ll have to work on it more if it’ll ever be finished, but it was a fun start!
