I decided to make the mock-up tank into a reality since I happened to have an extra white one around. Because the cotton was so thin the chemicals ran together more than I wanted them to but I guess it still kind of works since it gives it that inky feel. The Groucho Marx nose got a little lost so I might paint it on there. This photo was taken before the shirt has fully dried so the prussian blue might turn out a little lighter. It was exposed in the direct sunlight for an hour this morning- 9:30am-10:30am.
