A few friends have asked how to sketch graffiti. I started sketching graffiti in Junior High School to keep occupied (I usually sat in the back of the class). So here is a quick overview on how I sketch graffiti when traveling, the reason I mention that is to let you know that this is a more time consuming approach. Also, this type of sketching is for when you don't have anything but a pen and a "whatever type" (printer paper, napkin, math assignment, etc.) of paper handy. I'll only be using a ball point pen and and my sketch book(Sometimes I feel that using color in a sketch is too much of a time waster, markers, pastels and colored pencils never look as good as paint).
