Measure your round wire and mark it at 6 inches. Now take your round nose pliers, and grasp the wire deep in the jaw, on the mark. Bend the wire in half around the round jaw.

Next, place the middle of the hammered wire on the ring mandrel, at the size you want to make, and form the wire around the mandrel until the wire meets itself. Take the end with two wires and insert it through the wire loop. Hammer with a mallet to shape the ring.

Now take the end that you pulled through the loop, and form it in a loop heading the other direction, bringing the wire down. Trim so that the wire is 1/2" long, measuring from the loop intersection to the end of the wire.

Cut your half round wire in half, at 3 inches. Bend the half round wire in half with flat nose pliers and place it on the ring, about 1/4" away from the cut wire. Squeeze with flat nose pliers to form a wrap, then and wrap it 3-4 times as desired. Trim any excess wire. Repeat with the remaining 3" of half round wire on the other side of the ring, where the loop begins to twist.
