Each of the feet have holes which wire can pass through to be used to hang the piece. A short loop of wire is provided with each piece. It can be shortened if necessary. You can move the wire loop to a different foot if you prefer a different orientation. The other two feet will nicely stabilize the piece as it hangs from a single loop. You can also string a length of wire between two feet, though it might be harder to find comfortable balance point on the one remaining foot.
