painting on hoodies

[chiquita-bedita.livejournal.com]

i would really like to paint on a hoodie i have. and i mean like seriously paint something, not just a stencil. i know what paint i need and how i'll do it, it's just that how do i plan what i want to paint? is there a way i can draw on my idea easily? i'm thinking chalk possibly. any other ideas?

thanks in advance!
