Cut a 80cm length of blue cord. Tie a knot approximately 8cm from one end. Choose approximately 12 beads in a variety of finishes/tones and sizes.
Thread one bead onto the cord. Tie a knot just above the bead. Tie another knot approximately 4cm further along the cord. Add another bead.
Repeat these steps until you have completed the string.
Knot both strands together to complete your necklace.
