I love drawing with Sharpies. I have a huge set of fine point ones that I use to draw on pretty much any media... usually plastic though. For instance I've done tons of CD's.. I think I posted most of the real good ones in this thread somewhere. I'm to lazy to look them up so heres one of my favorites

I didnt date it but I drew this back in 2004. Around the beginning of my Senior year I loved doing these backwards drawings. Where instead of drawing with a dark pencil and doing the shading... you go with a white pencils on black paper and draw the lighting. This one is probably one of my best in that style.
