Measure the depth of the interior of the kitchen drawer.
Cut two pieces of 1-by-3-inch board as long as the depth of the drawer. These are the vertical dividers.
Cut two notches into one side of each vertical divider, 2 inches from each end, using a keyhole saw. The notches should be 1 1/4 inch deep and 3/4 inch wide.
Cut 2 notches into one side of each horizontal divider, 3 inches from each end, using a keyhole saw. The notches should be 1 1/4 inch deep and 3/4 inch wide.
Fit the four pieces together, turning them into a shape like a tic-tac-toe board. The notches hold the dividers together.
Place the dividers into the kitchen drawer. Because the wood fits the interior of the drawer, the structure is sturdy and can stand up on its own.
