They are also very easy to make. Grind a small "V" in the jaw of a lineman's pliers. Make it just deep enough to hold a piece of nickel silver wire of the size desired. Grip the wire (whole length) in the pliers and either peen it into a head, or use a head spinner chucked in a hand drill. Clip the "nail" at the bottom of the pliers and repeat. It only takes a few seconds to make a small decorative nail. Of course, anneal the wire if it was not purchased annealed.
