To repurpose this shutter, I used a piece of ceiling tile, a cabinet hardware (for embellishment) 3 cup hooks (in the center of the shutter) and 2 coat hooks at the bottom. Whenever I make a mail organizer, I use luan glued/nailed to the back of the slats. This prevents the mail from slipping out the back.
On this black mail organizer, I added the luan to the full length of the back. I added another cabinet hardware for embellishment, and small hooks at the bottom for keys and such.
These types of projects are very handy and versatile. My daughter has one in her kitchen, she uses it to cover up her fuse box.
