Prepare Materials: Gather all materials and tools. Start with about five feet of thread, adding more as needed.
Base Row: Begin by adding a stop bead to your thread. Create the base row using RounDuo® beads, Czech faceted rounds, and Miyuki seed beads in a repeating pattern, attaching the clasp with wire guards at the ends.
Second Row: Enhance the pattern by adding another layer of beads, creating a laced effect across the necklace's length.
Final Row and Cascading Effect: Introduce Miyuki drop beads alongside the existing pattern to create the signature cascading effect of the Mystic River necklace.
Finishing: Secure and finish off the thread using knots and glue at strategic points for durability.
