A couple hours while heavily distracted by Chloe playing the end of Kingdom Hearts I. I was experimenting with watersoluble ink on index cards, and the card didn't wrinkle, although it did get some weird texturing issues that I'm not sure about. SIGH. (I always like my results best on plain thin non-watercolor sketchbook paper, except they wrinkle hideously and aren't exactly something I could give away/commission.) (Bill Nye (the Science Guy) is not mine.)
