i textured the boards for the upper story. twice. (next time the instructions say to only grain one side i'm gonna grain both sides.)
then i let the boards soak in an a/i mixture of black and sepia ink. i let that dry overnight and noticed that the grain was barely visible, so that's when grained them the second time. then i applied the usual two umber chalks/alcohol, and now they're drying. the board at the bottom (reddish) is an o scale 2x6 i had on hand that was grained and soaked in the same mixture of a/i, and then chalk applied in the same manner. then i damp brushed a cheap acrylic paint (red iron oxide). i think that's how the second story will be. peeling red iron oxide paint with a peeling whitish color for the trim. this is a little more than half of the boards.
engine909 (the notorious ed) is supposed to be joining me in this build thread (he's way ahead of me, and what i've seen looks excellent), but he appears to be getting cold feet. some peer pressure and cajoling might be in order.
