desks, tables, platform beds, wall art and now... shelves. Click through the jump to see how you can easily and inexpensively, transform a hollow-core door into two floating shelves (and then install it!). First things first. Obtaining a door. Hollowcore doors can be purchased from your local hardware store and should always be in stock, however, you can usually find them at salvage stores and the ever-wonderful Craigslist. You can usually find them for less than $5 if you know where to look! We usually find ours at our local ReStore for $2-$3. They also store easily under beds and sofas if you come across one but don't have time for a project that afternoon.
Next you will want to locate the studs in your wall. If you have a wall that is "studless" you will want to take appropriate actions. Concrete and brick can use a hammer drill and masonry screws while walls with metal studs can use toggles to help hold things in place. Ask your local hardware store employee for which will work best for your wall.
After cutting your door in half using a circular saw or table saw (having another person around to lend you a hand is advised, but not needed), knock out a few inches of the support materials inside the door. Do not remove them all, just enough to slide a cleat inside in order to attach it to the wall (see below).
Measure the gap inside the door. Locate a wooden cleat that fits inside the gap and secure it to the wall.
Using a right angle and some brads, nail down your new shelf to the cleat. Your new shelf is ready to hold your favorite family photos or toys! To see the full step by step instructions (with more photos!) check out the full article by David Radtke over at Reader's Digest.
