The Designer’s suggested colors and materials:

Two sizes of Artistic Wire jump rings (diameters of 5.95mm and 3.97mm, both 18 gauge)

6mm Cube beads (crystal type is optional)

Two pairs of flat-nose pliers

Start with Small Jump Rings: Link five small jump rings to form a chain, then connect them into a circle using a sixth ring.
Form the Bead Chamber: Ensure three of the rings lie flat, with the others standing up. Connect the standing rings with new small rings.
Create the Tunnel: Use large rings to connect sets of small rings, forming a tunnel structure.
Inserting the Crystal: Place a crystal cube with a corner facing down into the tunnel, then secure it with large rings.
Secure the Crystal: Close the large rings over the crystal with a small ring to snugly secure the bead.
Repeat the Pattern: Continue adding sets of rings and crystals until the bracelet reaches the desired length.
