Not a lot of storage, but you can place them in random places with a few books & a knickknack. You can hang them like check marks or at a right angle. $6.99 at Ikea. They come in red, blue or green.

I did a similar thing for my teen sons room using his broken skateboards ( he himself had salvaged the wheels and trucks so they arent on) and "L" brackets which cost me $3.00 for 10 of em. The grip tape already on the top of the board helps keep things in place. I also hung his snowboard as wall art at his request. :)
There is no tutorial. These are a purchased item at this link. I like this idea for a nightstand by the bed. 8"x8" routered boards with 8" gap between shelves.
