Thought I'd cover some of the basic buildings I use in my western town. I tend towards california gold rush settings as I live about 90 minutes from Coloma, the gold discovery site, here from Sacramento County.
http://armoredink.blogspot.com/My wooden buildings are wood, from coffee stir sticks, wonderful material to work with, mostly straight, cut to standard lengths, can be bought in various lengths, raw wood so can stain or paint easily and cheap! I will post some stores soonish.
And there you have it.
