I purchased a cheap and cheerful.....If not badly made, tricycle planter! It was the nearest thing to a wagon I could find, since you can't seem to find those old horse and carts anymore :( ....I took the front wheel off, and the handle bars, which was easy as it was so badly made! I then started to add little bits and pieces to make the 'shelves. I had an old trinket box which I took apart and  glued on the sides of the wagon.

I broke up pieces from an old crate and cut them to make shelves.........
