By the time we got the sheathing on our house it was winter — too late in our rainy part of the world to take a chance on putting unfinished siding on the walls. So to keep the work progressing, I built a number of drying racks out of scrap 2x4s. As shown in the drawing, they have notches (cut with a dado blade) at 2-in. to 3-in. intervals. The notches accept the squared top edge of the lap siding. I arranged these racks in tiers on about 6-ft.centers in our unfinished house. This enabled us to prime both sides and paint one face of the siding while under a finished roof.
