Cones are versatile and commonly used at the end of multi-strand designs for a more "finished" look. They can also be used as a focal point in the middle of a necklace with a bead or pendant hanging from them.1. Complete your strands and crimp all ends. 2. Using 1/2 hard wire with a looped end, or an eye pin, put your strands on the loop and close it. 3..Take the wire or eye pin with the strands attached and insert the wire through the bottom of the cone and out the top. 4. Finish the wire end into a wrapped or simple loop and attach the clasp of your choice directly to the loop or a jump ring. 5. Repeat these steps for the other end.
