I'll go first;
I made a 3 incher and plucked out most of the face hair so that I could do some shading. Wow, it isn't has scary or hard as I thought- and it makes A HUGE DIFFERANCE. Thank you everyone- if you hadn't told us what and how you do it and then shared pictures I might never have had the fun of learning this new technique.
Now I need to make a slightly bigger guy and try it again
If you use oils to shade you can get incredible control, and very sheer layers, by using a DRY BRUSH technique. Am I starting to repeat myself and bore people yet? Just load your brush lightly and then wipe, wipe, WIPE until you don't think there's any paint left on the dang brush at all. It will be just enough to start you off with a wash of color. Keep on layering it until you get where you want to be, even adding white or cream if you get too dark or want some highlight, and you will see just how simple it really is.
If you're using acrylics, maybe someone else here has some technique suggestions for loading the brush and applying the paint...?
For sure, in either case, work slowly in sheer, light layers, and always brush through with a dry stiff paintbrush or wire brush when you're done, so you get rid of any "crispy-crunchy" feel the paint might have left behind. If you use oils and work sheer enough, tho, there won't be any of that at all. Just a wonderful layer of tint!
Shelli, as I started reading this thread I thought - "Oh yeah, someone posted something about paints and what and how to use them. I"ll never find that post though." So - REPEAT AWAY my dear!!! Thanks! Your description makes it sound not so scary if you can add color in baby steps.
