Project – leaf box

Next up, construct the inner frame using the off-cuts you saved earlier. First, measure and cut the pieces to length, then dry-fit them on top of the glass, around the inside perimeter of the outer frame. The distance between the glazing and back material dictates the front-to-back width of the inner frame, so cut the parts to fit. At the final assembly stage, the backing should sit flush with the back edge of the outer frame.

Simple butt joints using glue and nails will hold the inner frame together. When the glue is partially set, place the inner frame inside the outer frame to ensure it remains square as it dries overnight. Sand both frames before applying a finish.

Since pine is absorbent and of variable density, apply wood conditioner first to prevent blotching. To finish the frames, I used an oil-based stain in warm, reddish tones to complement the rich fall colours of the leaves showcased inside. After the stain, I put on a protective coating of oil-based polyurethane in a satin finish.

With the finishing complete, you’re ready to install the picture frame hardware that holds the back in place. While turn buttons are commonly used for this application, they’re difficult to find in stores. Save yourself the aggravation and purchase a package of heavy-duty picture-hanging eyelets instead. These can be used to hold the backing in place as well as to wall-mount your display. You’ll need six eyelets to secure the back. Remove the triangular hanging ring from the eyelet stem and fasten the stems to the back edge of the outer frame with the screws provided. If you don’t tighten the screws all the way, the stems will swivel around the screw. If you are wall-mounting your box, install picture hanging hardware as well.

When you’re ready for assembly, clean and place the glass inside the frame, then position the inner frame on top of the glass. Fill the box with leaves (see sidebar), and then install the back on top of the inner frame. Swivel the long side of the eyelet stems over the back and tighten the screws. Gently shake the box to distribute the leaves, then sit back and enjoy the view.

Preparing leaves for display

Sunny autumn days are a great time to rally family and friends for a leaf-collecting expedition. Although there are about 40 medium-sized maple leaves inside this box, the number you need will vary depending on the size and species of leaves you collect.

To dry and flatten the leaves, place them between pieces of absorbent paper. You can sandwich the paper between pieces of plywood weighted down with bricks, or you can place the leaves between paper towels and press them in a thick book. After seven days, the leaves should be flat and dry.

Lee Valley has developed a way to speed up the process. Its drying press, made with wool and broadcloth sandwiched between two pieces of terra cotta, can dry fresh flowers and leaves in just a few minutes while retaining their colour intensity.

After they’re dry, add a thin wax coating to each leaf. Do this by positioning the dried leaves between two sheets of waxed paper. Place a dishtowel over the waxed paper and press with an iron, set on medium heat, for about four minutes. This transfers just the right amount of wax from the paper onto each side of the leaf.
