I've been "stockpiling" these pen and ink drawings on watercolor paper. Each one is 4" x 6", and fits very well onto the front of a greeting card using photo corners. This makes a quick little gift that can be framed later (or exhibited on the ULTIMATE place of honor---THE FRIDGE!).
I keep small projects like this in a portable folder so I can fill empty time by "doodling" -- then paint them later. It keeps my imagination flowing!
I think it is important to share our process with others, just as we gain from watching other artists work.
