Desired fabric (enough to cover all plywood
Staple gun & staples
L brackets (4)
Waverly Home Decor Fabric in Piazza Stripe Vapor $23.99 per yard
1/4" Plywood from Home Depot
Initially I tried gluing together the end pieces to the main but they kept breaking apart. I finally purchased some wood screws from Walmart for $1.97 and screwed the boards together. I also picked up L brackets for $2.98 and some wall screws with anchors for $2.97.
From there, I measured my fabric around the cornice and staplegunned it around. You can also use batting but I chose not to for this project. Make sure to leave some room to screw in your L clips on the top and bottom of each side panel.
I hung up the boards using the L brackets on the top and bottom. Total project cost to coordinate with my chairs = $94.90.
