I had a few wine barrel staves and decided to make it look like a crown. I screwed in the staves on top and bottom. Then I took my daughter's old train set and nailed that to the wall to connect on top. The fleur de lis parts are made from cardboard and spray painted. The light behind the bottom part is an led light I bought and kept it on with rubber bands.
The second part with my bike was an old fence from outside. I just drilled it into the wall then put some hooks on it and it is really supportive to hold my bike. I took old wheel from a skateboard to hold up the razor scooter.
