All About Stenciling

as a long time fanatic of street art (graffiti, stickets, etc), i've finally decided it's time to make a little of my own. i know what i *want* to make, but i don't know *how* to get what i want out of sharpies and spraypaint. i have a couple stencils made up, but nothing too complicated. any advice? any sites that could help me out?? thanks!

ive been doing graf and just draw till you find

1st off, best of luck, and enjoy :) 2nd, why not "experiment"... the whole point of art is to find, dont go by others limits, explore for yourself, create your own way of "how"... peace and cheese grease!
