During my wire work classes I always express the many creative ways to use the components I teach. Each wire configuration can be converted into a design, big or small, to add to your artful jewelry creations.
The Caulder Bead is universal and it can be used all through out a necklace. It also can be a single pendant for a chain.
Use 16 or 18 g wire. Cut 8 inches. Don't forget to file down the ends of your wire with a #2 jewelry file. Find the center of the wire and note it by bending or marking the wire.
Begin with using your round nose pliers and make a circle on both ends of the 8 inch wire. Begin using the flat nose pliers to coil the wire holding the pliers flat on the coil and wind until you get to the center of the wire. This is flat at this time. Then begin to wind the opposite end to create the beginning of your Caulder Bead. You can use this as shown or continue to make a complete Caulder Bead. 
Using your round nose pliers push out the two circles or coils making them appear to be cones. Using your flat nose pliers bend center of the wire around to create the complete Caulder Bead. I call this closing the circle or cone. It is simple when you think of bending the cones together at the center or the mark you made on your 8 inch wire at the beginning of this process.
You can create a complete necklace just connecting these wire beads together with the jump rings I wrote about in a previous blog posting.
You may encase a glass, wooden, clay or any other bead with a Caulder Bead. Do that by slipping the bead inside the two coils before you bend them together to complete the coil wire bead.
