The Cardboard Challenge attracts younger children. But that shouldn't stop teens from taking it on. When I was in college, I chose cardboard for a project and serious artists are doing amazing things with the medium. Check out these sculptures by artist Chris Gilmour.
The thing I like most about IF's project is that it encourages collaboration between generations and people with various talents. And it's fun. The fourth challenge officially kicks off in September, 2015, but why wait? Gather friends and neighbors of all types and ages. Get parents, mentors or teachers involved (you'll need a sponsor and gathering site). Brainstorm ideas, draw up plans, and wow us with your cardboard creations. You can even use the event to raise money for IF's scholarship fund if you want, and there's a contest for best video. Here's a link to FAQs about joining the challenge.
So teen artists, why not cardboard? It definitely made a difference in Caine's life.
