Make cute garden signs by sanding down old wood boards, adding a base layer of paint and painting on some sayings or pictures. Break overly long boards by placing them on a cement block at the desired size and stomping if off. Sawing the board off also works, but it doesn't maintain the board's rustic look.
After cutting or breaking a board to size, drill two holes on either side for hanging, and sand down the edges. Clean off the dust, and add a layer or two of patio paint. After the paint dries, sand it again for a worn or antiqued look, paying special attention to the edges.
Before painting on the garden sayings or pictures, pencil in the desired designs. After the paint dries, twist the ends of a length of wire into the holes so that the sign can be hung from a curved metal stake. The signs can also be attached to repurposed wooden chair backs.
To make cute garden signs to mark certain kinds of plants, write the name of the vegetable or herb on a tiny upside-down clay or terracotta pot, and hang the open side of the pot on a wooden stake or twig.
