Two good methods have been presented in rec.games.miniatures. The first comes from Steven Loren Lane, and is used without permission: % "Well, on top of getting the smallest brushes available, you can always cut them down to an even smaller size. I have several brushes that have only a few hairs on them. These are very useful brushes. I would also recommend for the very fine detail to set the object up so you can use both hands to hold the paint brush as still as possible." And was followed up by Steve Gill: % "Another useful tool is a 0.13 mm spirograph ink pen, a couple of splodges of colour in the right place and you can pretty it up with the pen. I used this technique for 6mm heraldry." Yet another use for tech pens. They are also very good for shield devices and clothing patterning.
