The fork is made by creating a wire loop out of two wire clothing hangers, then winding it up around a mandrel and trimming the excess.
Starting with two wire clothing hangers, clip the hook off the top. Using pliers create hook at both end of each wire. Connect the ends together by interlocking the hooks and crimping the ends. It is easier to turn the wire hangers 90 degrees from each other when connecting and crimping.
Straighten the loop so that the hooks are at each end and the middle is relatively straight. You just need to do enough to make the wire easier to work with. The winding process will finish straighten the wire;
