Winter Camoflauge

I think most people do a whitewash with thinned white, maybe a few light coats till you get it where you want. I use a technique where I use flat white right out of the bottle in almost a drybrush (just a little wetter) hit a towel with the brush then the model and almost punch the brush into the model lightly, small section at a time until it is built up to where I want the white.  I would practice this on a piece of cardboard or something to get the feel. this is not painting mind you, it is a dryer technique. Good brushes are a must.
