In a previous topic I wrote just for fun that you'd have to use square flat tipped brushes, but that's exactly what I'll try on my next figure: Tamiya's 1/16 US soldier in Iraq, which I'd like to paint as a Marine (BTW is this figure's gear compatible with a Marine?).
I'm planning to modify a small brush cutting the hare and making the tip square.
I'll let you know how it works.
