Lovely depiction of Indo-Arabic style in unique colours and VERY hip canvas! I'm so copying this. BTW - RAWKS! You have to let us know how well it does in the auction. And not only does your art rawk, you rawk for doing it for charity!
Cut it out and stick it on a shirt that you like that fits you! Sew it on, baste it on, pin it on with those little tiny gold safety pins. Or you could edge it in grommet tape, put it on the back of a hoodie.
