To keep the spice boxes in a handy place where they would be together and not behind larger articles on the cupboard shelves, I made a special spice-box shelf, as shown, to hang on the inside of the cupboard door. The shelf swings out with the door as it opens, and is made of two bracket ends to which a bottom board and front crosspiece is nailed. The size of the shelf and its capacity are only limited by the space on the door. - Contributed by Austin Miller, Santa Barbara, California.
