Draw up a plan of how you want the shelves to go around the room. Here think of whether you want the shelves to be scattered or around the room in a line.
Cut a thick piece of solid wood, such as oak, approximately 2 feet long, 1 foot wide and 2 inches thick. Use a power miter saw to make a clean cut.
Drill a hole slightly larger than the screw head you’ll be using to attach the floating shelves at the center of one of the edges of the shelf, about 2 inches from one end.
Repeat Step 3 on the opposite end of the same edge, about 2 inches from the end.
Drill two screws with a drywall stud into the area where you want to install the floating shelf. They must be at an equal distance as the holes on your shelf.
Sand the shelf using sandpaper until the entire surface of the shelf is smooth.
Finish the shelf with wood finish, stain or paint.
Attach the shelf to the wall by driving the screw heads into the holes drilled during Steps 3 and 4.
Repeat Steps 1 through 8 around the room wherever your design indicates.
