Dry brushing is an extremely simple and easy way to add scratch marks around your kit or depth to its internal frame. What makes the process easy is that you only need a brush and some paint. What makes the process special is that you’re applying the paint when it’s nearly dry. This allows for only a little bit of paint to be applied at a time and in thinner, narrower streaks than you’d get with regularly applied paint.
Dry Brushing the Internal Frame
The only equipment you need for this method is stiff bristled brush, some paint, and paper whose color contrasts with the paint you’re using. I like to use an old toothbrush and save myself the trouble of buying a brush just for this purpose.
