During the nineteenth century, pinwheels were invented as children's toys designed to spin in the wind. However, any experienced vegetable gardener will tell you how effective pinwheels are at keeping birds and other critters out of the garden, plus they add a decorative design with the polka-dots, circles, and striped patterns. Bring some color into your miniature fairy garden, by choosing a blue, yellow, or fuchsia mini Pinwheel to complement flowers in bloom. The metal Pinwheel can also be used to guard the vegetable garden. When a gust of wind comes up to spin the pinwheels, the motion will surprise an unsuspecting mini bunny who is munching on the nearby crops.
