Working on one side at a time, glue and nail the side to the back. Apply glue and drive three 1-5/8-in. nails into each shelf, attach the other side and nail those shelves into place to secure them. Clamps are helpful to hold the unit together while you’re driving nails. Center the top piece, leaving a 2-in. overhang on both sides, and glue and nail it into place. Paint or stain the unit and then drill pilot holes into the top face of each side of the unit and screw in the hooks to hold your ironing board. Mount the shelf on drywall using screw-in wall anchors.
Cedars are strong, aromatic softwoods that are capable of enduring outdoor elements, the most common of which is the Western Red Cedar. Western Red Cedar can sustain wet environments without succumbing to rot, and as a result is commonly used for outdoor projects such as patios, outdoor furniture, and building exteriors. This wood can be easily found at most home centers for a moderate price.
