I just had to share the TP castle, which first was a pirate ship with canons. Great example of children's imagination with cardboard, eh? At first I wasn't sure why my son wanted us to save all of the TP rolls, but here's what he came up with. He loves it, it is his pride and joy when people visit his room. He even brought it for show-and-tell.
Just goes to show, you can make anything out of nothing...
