Sharpies write on plastic sandwich bags rather nicely. When pulling parts off my vans, I often times will stick the nuts and bolts and what not into plastic sandwich bags, and then right on the bag what the part is from/for. Saves a lot of time later on when putting things back on.
(like where did this nut come from? Oh, starter motor nut.)
