For each lure, slip a split ring through all four holes. Split rings, swivels and hooks can be bought anywhere fishing lures are sold. At the tip end of the spoon and the narrow part of the handle, slide a swivel through the ring. At the other end of both, slide your choice of hooks through the ring. Attach the hooks using needle-nose pliers to avoid hooking your fingers.
If you paint one side of the lure with high-quality gloss paint, it will produce contrasting colors when the lure rotates in the water. Paint the lure long before you plan to use it so there will be no paint odor.
When you catch a really large fish, be sure to casually mention to anyone nearby that you caught that monster with a spoon!
