I decided to try this with my kids.
I had them write down a list of different emotions which we put in a hat. Then they took turns posing for pictures while the other one pulled an emotion out of a hat. The kids really had a great time with this. Once the pictures were taken, I converted them to black and white and played with the exposure a little in Photoshop. After that, it was off to get canvases, which I bought at Michael's at a great deal. The edges were painted black and the pictures were glued and sealed onto the canvas with Mod Podge.
The results were great and perfect wall art for a blank wall.
