Add a rustic touch to your garden with a DIY bird bath made from a vintage metal tray. Look for a tray with a weathered patina or interesting texture. Attach three or four metal legs to the bottom of the tray using screws or bolts. You can repurpose old table legs or use metal rods. Place the bird bath in a sunny area of your garden and fill it with water. The birds will be attracted to the shiny surface of the metal tray and enjoy a refreshing bath. The rustic charm of the vintage metal tray will enhance the natural beauty of your outdoor space.
