Cut Wood

Use a circular saw to cut the pieces based on your measurements. Make sure the plywood is cut so it covers the entire back of the frame.

Sort Wood Pieces

Be sure to keep your pieces organized. By grouping the pieces for each shadow box, there can be no confusion as to which piece goes where.

Sand the Edges

Use sandpaper or a sanding block to smooth out the edges of each piece of wood; this will prevent sharp corners and splinters.

Apply a layer of primer. This will make your paint color more solid and add a layer of protection.

When the primer has dried, move onto the real paint. We chose white for the frame of the shadow boxes and various shades of vibrant colors for the back panels. Let the paint dry before moving onto the next step.

Assemble the Frames

Glue together the four pieces of the frame. The two longer pieces should be glued to either end of the smaller ones, making a rectangle/square.

Glue on the Back Panel

Apply glue to the backside of the frame, use your finger or brush to smooth the glue evenly on the surface. Place the back panel face down (the painted side) on the frame.

Add Wall Fasteners

Adhere the wall fasteners onto the backside of the frame, towards the top. By using stick-on fasteners the shadow boxes will be super easy to hang, and won't leave any holes in your walls. Make sure the fasteners can hold the weight of the shadow box and what you plan to put in it.

Hang the Boxes

Use a level while hanging your frames to make sure they're even. It's the extra attention to detail that makes them look professional.
