To conceal hardware, place bolts in between the two layers of plywood so the threaded ends stick out of the backside. Before you finish the backside of the footboard, upholster the front side. Refer to Upholstering a Curved, Diamond Tufted Headboard for instructions on completing various types of upholstery constructions. Staple webbing to the frame of the footboard and stretch to the opposite side with a webbing stretcher. When the webbing is to the desired tightness, staple and cut off the excess 2” beyond the staples. Fold back the 2” excess and staple again. Continue stapling strips of webbing vertically and horizontally across the frame. Space strips 4” to 6” apart and basket weave them as you go.
