While I've got a couple of real good books on scenery techniques, and am rady to begin those steps, I am still stuck on the decision between adding the base paint / texture / step or the hill / mountain / tunnels step. These guys writing these books are pros and seem to do both, mentioning neither as a first step but showing both as a first step. I know it's up to me, what ever I want, etc, etc. But there must be SOME rule of thumb on this subject. Once ballasting is finished... what next?
