I picked up a box of Platinum Carbon Black cartridges at a local art supply store yesterday. It's waterproof, so I thought it would be a good tool to have when I'm out and want to draw something to paint later.

I was holding out on trying Carbon Black because it tends to dry out from neglect in speedy fashion, and I'm a professional art supply neglecter (real title, it's on my resume). Fortunately for me, Tina Koyama's idle testing found that Platinum pen caps seal tight enough to keep even pigment-based ink wet for months. I had a spare Platinum Preppy laying around, so it's the designated Carbon Black pen now (and until the end of time, probably)!

I got lazy mixing colors, so I used a whopping ten paints (not counting white). I panic-added yellow gouache at the end because I didn't feel like the chili oil was orange enough, and I don't have yellow watercolor... Perks of only using secondhand tubes!

I've been thinking about my sketchbook in terms of "how" instead of "what": I pick a medium or color palette I want to experiment with or improve at and dedicate the entire spread to that. It's helped me avoid succumbing to perfectionism-induced decision paralysis because I just think about cool stuff I want to try instead of getting stuck on making a pretty picture.
