If you have an old piece of wood, tear a piece from it to make a sign. My piece came from an old fence I tore down after I moved into my house.
I stained the wood with watered-down turquoise acrylic paint, and beach was written on it with pencil, followed by painting over the pencil with white acrylic paint.
I attached chicken wire, and now, the rustic recycled wood sign hangs in my living room. I like the natural, simple look and the ‘beachy’ feel I get looking at it.
