I probably don’t need to comment on the weather – other than you know it is muggy when you get out of the car and your glasses fog up. Or when you walk into the barn and see the bricks on the floor are wet. Or when you stand in the shade staining windows and the sweat drops off your nose, ears, and arms.
The hay rack is a great place to finish/paint stuff. Here is the big window for the attic dis-assembled.
To try to match the original aged woodwork (pine and fir) in that carmelly old color, I had a custom stain mixed, apply a couple of coats of orange shellac and finish it with a couple of coats of poly. It’s a lot of work, still not exactly right, but much closer than I can get out of a commercial finish.
