How to Build Corner Shelves

Cut a section of wood into a triangle and hold it tight against the corner where you want the shelf to go.

Set your protractor so the ends are close together. Run the pointed end along the wall and the pencil across the wood. This transfers the shape of the wall to the wood, so you can build a corner shelf that fits perfectly.

Use the saw to cut along the line you drew with the pencil. Lightly sand the edges of the shelf.

Paint or stain your corner shelves to suit your decor.

Screw support pieces of wood to the corner where you're going to install your shelf. Paint them the same color as the wall so they disappear once you install your corner shelves.

Hold the shelf tightly in place and drill up from the bottom of the supports and through the bottom of the corner shelf to secure it in place.
