Glue and mount the shelf inside the leg notches, and secure it through the legs with 2½-inch trim-head screws. To make the apron that sits between the legs, cut two 2x6s to 40 inches and two 2x6s to 27 inches. Attach the apron using surface-mounted corner brackets; shave a slice off the top corner of the leg to flatten it so that it fits against the bracket. Fill the screw holes and the seams between the 2x4s on the legs with wood filler. Let dry. Sand with fine-grit sandpaper, prime, and paint the frame.
