I do Graffiti art work, and need ideas?

[gangsta]

i do graffiti art work, i've been doin it ontypically flat wood, wood signs, friends walls, and paper but recently my customers have been wondering if i could do my work on tee shirts. I think that would really expand my options. but wut sort of paint would I use for a tee shirt and still have the control of it to do my work, like an airbrush type of thing? i dont want it to be like puff paint or spray paint on a shirt because that gives the shirt that nasty stiffness and crappy look. Where could i get like a airbrush set that would be durable on clothes through wash and wear etc. and still give me that spray painted look? any help would be appreciated


also any ideas that you have that you think would be cool as a customer, or that would be a hot seller, im open to any sort of ideas from the public.
