The Tabletop Titans site has a photo tutorial on inking miniature wargames figures. Inking is a great technique — actually a great time saver.
Tabletop Titans has a tutorial on using inks on a white base to create a sort of “watercolor” look to your figures. I very much like the look and am trying to decide on what unpainted project I could use the technique. Actually, I’ve been thinking about getting some of those woodland creatures figures and doing a “Mouseguard” game. The watercolor look would be just right for that.
