Unlike most windows on the interior of homes these days, our windows will not have trim around them (it was hard to picture what it would be like). Instead, they will have drywalled jams. So before we drywall them, we must bring up the platform for the drywall to sit. My Dad is seen here attaching 2" x 3" plywood rectangles for that reason. Lots of work, but every little step brings us closer to seeing rock on the walls.
