Here's how it turned out:
My husband helped me by making a stencil for the little t-shirts, and my Mom helped me by finding the miniature soap boxes at a local laundromat - I guess you could call it upcycling, because they came from the trash. :) I used my Cricut to cut out the subjects in 6 different fonts. I also borrowed an idea to use green tissue paper for grass instead of using a ton of green paper or cutting blades of grass.
And here's a card I put together yesterday for my stash - no challenge, just for fun:
I love the "cartoon talk" stamps from Michael's and can't wait to use more on future projects. The notebook edge punch is from Stampin' Up and the star dies are from Sizzix.
