POSTER PAINT ON CULTIVAR OF SQUASH PLANT.
I hadn't painted in so long since starting university that when I was given the opportunity to "supervise" the "pumpkin painting" during MIT's SaveTFP's Halloween celebration I was very excited. After an hour of setup and making woollen pom-poms to serve as pumpkin hair (they were quite cute), I bunkered down and started illustrating my own pumpkin.
I don't think I was a terribly good assistant at the event, since people seemed to be getting along perfectly well without me, but I had a really good time. Also, the pumpkin survived longer than I expected. Two months and still going strong.
(I wasn't quite sure how to sort this. It's not an illustration, nor is it a painting, really... it is simply what it is. Since it was fun to make, and sketches are fun, it's a sketch. On a pumpkin.)
