I grew up always hearing "when pigs fly" something will happen. Well, there are things happening nowadays that I never thought I would see, so as a joke, I made one of these and hung it on my porch. It has been such a conversation piece. This wind spinner/wind catcher is made so that it will gently spin in the breeze without any noise, and I get to tell people that I have "flying pigs", so anything is possible. Each pig measures 4-1/2" wide by 4" tall and are connected with swivels so that each one spins independently. The overall length of the wind catcher is 26" long. The pigs all have a rusty patina started and can be left to continue rusting or sprayed with a clear coat to inhibit any more rust. Can be hung inside or outside. Each one is unique, so no two will have the same patina.
