We hung over 80 feet of 4-foot-tall bead board in the garage. The board has little grooves every 1.5 inches. The grooves had to be painted by hand, as a roller would not effectively cover them. So that’s over 640 48-inch grooves versus me and a paintbrush. My wrist no longer functions in the traditional sense but I won. A half-mile of grooves can suck it.
