Silk is traditionally the best material to use for stringing valuable beads such as pearls, coral, amber and jade. It is soft, strong and drapes well. It does not damage softer beads. The Griffin Jewelry Silk Bead Cord is made in Germany from 100% high-grade filament silk tightly twisted into a 3 ply cord. It is available in 13 colors created to coordinate with gemstones as suggested by their color names. It is a good silk to string beads, for bead crochet or any other projects requiring a strong high quality silk. It comes on spools with enough yardage for many projects.
Griffin 100% Natural Silk is usually available on cards as a 2-ply cordon with a needle attached to its end. The cards are only 79 inches (2 meters) long. It is often too short for longer necklaces and for application needing longer cords such as bead crochet. One of the way to get around this, is to make your own cordon.
Use the Griffin Jewelry Silk to make your own 2-ply cordon, add a collapsible needle and get what is available on a Griffin Silk Card but with the exact length you need for your project. A cordon is a two-ply made with a cord, twisting in the same direction of the cord. So since the Griffin Jewelry Silk 3-ply cord is twisted counterclockwise, make sure to twist in the same direction as shown in the illustration below.

I find the easier way to make a 2-ply cord is with at least two stationary hooks. Tie one end of the cord to the first hook. Wrap the cord around the second hook. The tie the end to the hook on your mini-twister or your cordless drill. Twist the cord counterclockwise until it starts kinking. Fold it onto itself. Tie it together and let is twist clockwise by itself. If you need a needle, attach the needle before laying the odd together and place it at the center hook, where the cord will fold onto itself.
Two-ply cord can be made out of many different types of cords, not just the Griffin Silk. The mini-twister or corder shown above is a good hand tool to use. Reversible drills with a hook attached are best for long cords.
