How to Make a Full-Size Mirror Frame

No need to splurge on a large, notice-me mirror when you can fashion your own frame from plywood.

This mirror lends dimension and brightness to any space and brings welcome height when paired with short furniture. Routed edges and scalloped corners play as wall art by framing reflected objects. When paired with colorful decor, a natural wood stain prevents a bold mirror from stealing too much of the spotlight.

How to Accessorize with Decorative Mirrors

What You Need

  • Straightedge
  • 81x45-inch sheet of 3/4-inch birch plywood
  • Measuring tape
  • Round trash-can lid
  • Drill and 1/2-inch spade bit
  • Jigsaw
  • 1/2-inch cove router bit
  • Router
  • Sandpaper
  • Cloth
  • Wood stain
  • 66x30-inch mirror
  • Mirror clips

Step 1: Mark Border

Pencil a 9-inch border around the plywood using a straightedge, being careful to mark straight lines as a good guide for later steps.

Step 2: Mark Scalloped Corners

Create the scalloped detailing by measuring and marking 13 inches from each corner of the plywood in both directions. Position a round trash can lid so it lines up with both corner markings, and trace around the lid with a pencil, stopping when you reach the border lines.

Step 3: Cut Out Center

To make it easier to start cutting out the frame's center with your jigsaw, use a drill and 1/2-inch spade bit to create holes 1/4 inch from the inside of the border line as well as at the corners of each scallop. Then saw along the lines, keeping the cut as straight as possible.

Step 4: Router the Edges

To create the frame's inside edge detail, insert a 1/2-inch cove bit into your router, and set it to a 3/4-inch depth. With the router's baseplate flush against the mirror frame, gently move the bit toward and then along the inside of the frame in a clockwise direction using steady pressure.

Step 5: Sand and Stain

Sand any rough edges on the frame. Then apply a wood stain or paint according to the manufacturer's directions. If using an opaque paint, prime and then paint for an even finish.

Tip: Give your frame a worn, weathered look by applying a gray stain and then wiping off the excess after a few minutes.

Step 6: Secure Mirror

Arrange the mirror on the back of the frame so it overlaps the frame by 1-1/2 inches on all sides. Secure by placing three mirror clips on the long sides of the mirror and two clips on the short sides.
