Wanna expand your shelves? Here's Martha's take on on completing the task with ease.
1. Select plywood the same thickness as sill; cut it as wide as sill and 12 inches deep.
2. Attach bottom of shelf to bottom of sill with 3 hinges: 1 at the center, the others near the sides.
3. Cut 2 right triangles from wood thin enough to lie flat beneath folded shelf; trim tips. Brackets should extend 3/4 of the way across shelf and 3/4 down apron.
4. Hinge brackets to apron. Paint before installing.
