Materials & Tools:
- 2 med-duty hinges
- Sewing machine
4) Measure the length and width of the bottom of your ottoman. Cut plywood to fit. (The thickness of your plywood will depend on how strong you want the floor of your ottoman's interior to be, and also what kind of legs you have for your ottoman. In this case, my legs had fairly short screws, so I needed my plywood to be strong as possible, but also slim, so I chose to go with 1/4" hardboard.) Position your piece of plywood on the bottom of your ottoman, mark and drill holes of appropriate size to fit your legs.
Screw legs into position to make sure everything fits, make adjustments if necessary.
5) Using legs to hold plywood in place, drill holes around the outside perimeter of the plywood, and secure to ottoman frame with screws.
7) Replace bottom covering and legs.
11) Cut a piece of black lining fabric and stable to bottom of ottoman top to cover plywood and fabric edges.
12) Measure length and height of each of the interior walls and floor of the ottoman, adding enough for seams. Cut out pieces of black lining fabric in accordance with your measurements and sew a case lining for the interior of your ottoman. Place inside of ottoman and secure to ottoman frame around upper and lower perimeters with staples.
13) Position and secure hinges with screws to outside edge of ottoman lid (on the plywood). Position and secure remaining side of hinges to ottoman box frame with screws, checking to make sure that lid will fit correctly on the ottoman box when closed, adjust if necessary (You may need someone to hold the ottoman lid for you while you do this).
