Doodles 1+2 are watercolors using a cheap set I'd bought 2 years ago and never tried. The colors scanned horribly, and I'm hoping my better watercolors will reproduce more accurately. Today I learned that scanning doodles is a lesson in reproducing color (don't have high expectations and you will be a better person for it).
Doodles 3+4 are self-explanatory.
Doodles 5+6 were using whatever was on the kitchen table at the time.
