Add a touch of whimsy to your garden with a DIY driftwood wind chime adorned with seashells and beach treasures. Start by finding a sturdy piece of driftwood that is long enough to serve as the base for your wind chime. Clean the driftwood by rinsing it with water and letting it dry in the sun. Next, gather seashells, small pieces of driftwood, and other beach treasures that have holes or can be easily drilled. Use a drill to create holes in the driftwood and beach treasures. Attach the seashells and beach treasures to the driftwood using fishing line or sturdy string. Tie the fishing line or string securely to the holes in the driftwood, making sure each seashell or beach treasure hangs at a different length. Once all the seashells and beach treasures are attached, hang the driftwood wind chime in your garden and enjoy the soothing sounds it creates as the wind blows.
