It takes some practice to become adept at wire wrapping crystals and rocks, but the good news is that there is no wrong way to do it. Your wire can be wrapped neatly and symmetrically if the shape of your stone will allow it, or you can go for an interesting, messy pattern. Wire wrapping crystals makes for easy stringing on necklaces, bracelets or other accessories.
Cut about a foot of wire from the spool.
Place the wire vertically along the side of the crystal you want to use as the back, leaving an inch of wire protruding from the top of the crystal.
Bend the wire with your finger just around to the front of the bottom of the crystal, keeping the back piece in place with your finger.
Hold the crystal in one hand, continuing to secure the wire to the back, and begin wrapping the wire around the crystal, on the outside of the back length of wire. Leave however much room between rotations as you'd like -- it's up to you how much of the crystal shows through the wire. Wrap tightly so the crystal will remain secure, and keep wrapping until you reach the top of the crystal.
Twist the remaining wire twice around the excess inch of wire from the other side, like you would a twist tie from a bag of bread.
Wrap the small end of wire around one of the ends of the needle-nose pliers. This will be the hole you'll use to string the pendant, so make sure you make it big enough to slip onto chain or cord. You can do this by using the appropriate-sized section of the pliers.
Wrap the excess twice around the spot where you twisted the wire in step five above, and snip off any extra wire.
Hold the loop perpendicular to the crystal with the flat-nose pliers. This will allow you to maintain the shape of the loop and give you the resistance you'll need for the next step.
Take the long end of your wire, and wrap it neatly around the area between the top of the crystal and the loop you just made, covering and securing the area.
Snip off any excess wire.
