Add lattice and final pieces
Cut the lattice supports to fit snugly between the posts behind the bench. Attach by drilling angled pilot holes and driving
3-inch screws. Cut the lattice panel to fit, and attach by driving 1¼-inch screws into the posts and supports.
Use a power miter saw or a circular saw to cut the ends of the 2 by 2 verticals and slats at a decorative angle. Using 3-inch screws, fasten the four verticals in place inside the cross braces on the side opposite the bench. Screw the eight slats on top of the beams. Screw the decorative corner braces in place. Finish the arbor with stain, or apply primer and paint.
