All you need are these:
glue gun & glue sticks
simply cover the cardboard with your chosen old jeans.
By using a blade, make a small hole (about half inch of size) on top of the covered cardboard.
When you finished covering it, if you want it to be customized and have it designed, just grab anything from your cabinet. I found my damaged hair clip and ribbon from my drawer. Just glue them (decorations) anywhere you want to put them.

And this is the result. Intresting? =)
Have fun on recycling stuffs. It's better than having expensive ones. This will also lessen your trash, right? =)
