We are refinishing our staircase and I'm looking for a rustic contemporary all wooden balluster and railing source. I'm looking for clean block style with no carving or feathering or other detailing just straight and plain and unfinished. Most sites show either very traditional carved natural wood and white painted or wrought iron. To me, these are not contemporary or what we're looking for. HELP! We're located in SF Bay area but open to online vendors.
