I've always been interested in graffiti, but never knew too much about it, I told a friend of mine I was thinking about trying it, and she asked me a question that forced me to research it.
She asked, are you just going to do this freehand?
At that point I had little clue what she was talking about. On one hand, I was aware of stencils, so that could have been what she was asking. At any rate, I knew I had to do some research. What I learned about didn't have much to do with her questions, so to this day I kind of think she didn't know much either. Still, I learned a lot about different types of paint and possibly more important, different types of caps.
This website is dedicated to what I learned from my research, and from my experimenting with paints.
