A few years back, my county library system held an art competition. It could be a depiction of anything that you wanted, it just had to include something recycled in it. If you won for your age group then your work would be featured on a bookmark and your work would be displayed in each library for one year.
I designed a robot that used old wool, old stuffing, old buttons (seriously that gear button is from a shirt of Kevin's he owed when he was four), as well as scraps of fabric for arms and legs.
Because he is such a marvelous work of recycled genius, I ended up winning first place! (I may have been the only one that entered for my age group...)
