I just started graffiti a few days ago and want to know how to practice at home? I don't have any paint, so i want to know how i can practice on paper with a sharpie. I'm goin bombin on saturday with my friend cuz hes been doin graff for awhile. I've been copying other peoples alphabet and have come up with a few of my own and have been copying a lot of good throw ups but what else can i do.
