3 Step Bone (simple version)

Bone painting seems to come up often on  the mini painter list that I am a member of.
 Everyone has their own way of painting it, but here I am going to let you know how 
 I do it. I think it works quite well, and  not very difficult to do at all. 

STEP 1,is...clean the mini!! remove flashing, file down mold lines and injection areas. 

STEP 2, paint all the areas you want  to paint bone, with GW's bubonic brown, 
or Coat d'Arms festering brown. I prefer the older GW paints, or if you cannot
 get them anymore, find the Coat d'Arms stuff at Brookhurst hobbies

 STEP 3, Wash heavily with GW chestnut wash.    When I say wash heavy,
 I mean wash heavy. Use it as a stain to change the color of the bubonic brown. 
Make sure the recesses get covered. 

 STEP 4, Ok, I goofed, 4    steps if you add in priming. Dry brush with GW bone
 (old style paint, not the new crap in those dry out quick bolter bottles.) 
Working slowly to bring up    the bone color, since you can always add,
 but not take away. Once your happy  with the look, or degree of
 bone vs. dark brown, STOP! Try to remember when  to say when, overpainting
 will just obscure the effect you are trying to achieve.
   

STEP 5 WHAT? another step? well, this is  for cleaning up the work.
You can use a fine detail brush to add some chestnut wash to the deep
 recesses.

 This might seem like a lot to do, but try it once and you'll be surprised
 at how easily this can be done. Enough rambling for me. Hope this
 helps all the aspiring bone painters out there :-)
