I'd been forewarned by some of my friends that Magic players like to get cards altered at tournaments. Rather than make a mess of things with a Sharpie I took some acrylics to October's Toronto GP, so I could make little paintings like these:
A few people were surprised I'd only been using acrylics for a few hours, but they trusted me with their cards anyway. Back home I decided to try them at a slightly larger scale -- and to compare my M. Graham acrylics with the newer Winsor & Newton Artists' Acrylics. Both boast longer open time than older acrylics, and WN's claim of minimizing color shift during drying was interesting. So during an evening at Tom's studio with Greg, Ben, Allen, and Chris, I did.
I think the M. Graham paints' longer open time was more important to me than the lack of color shift in the Winsor & Newton paints. In the end, though, I was glad I could go back to oils.
In conclusion, napkin doodles:
