I had purchased a couple vintage metal trays a month ago because I had an idea about a memo board for recipes, pictures, phone numbers, etc.
I chose the pink tray (love the salmon-y, thistle-y color!) and glued a dark ribbon to the back. Simply hung from the wall and added a large vintage button over the nail head. (It looks like a huge licorice gumdrop). An etsy.com store (daysmadesweet) sells very powerful glass magnets in cute patterns. Mine are black with white polka dots.
Looking at this photos, I realized it is hanging a bit crooked. Off to fix it now. Maybe this will inspire someone out there.
