So if you haven't heard of Wargames Painting and Modelling (online magazine) yet, go check it out over at http://www.thecourtjestersstudio.com/WPM/home.html
Great articles all dedicated to the art of painting figures (of all scales.)
AND ... in issue 3, is an article on painting miniatures in black and white..by me :) I hope you enjoy.
I like the magazine both for its content and its use of LARGE photos so you can see exactly where the paint is being layed down on the figure. The magazine also takes contributions and offers free advertising (for wargames and miniatures companies that is.)
