Cut a length of 1.5mm leather cord double the length of the bracelet plus an additional two inches.
Attach the leather to the two-hole clasp, creating a loop at one end.
Using a size 10 needle and 0.008" Wildfire thread, begin sewing 4mm lava stones between the two leather cords, ensuring even spacing for flexibility and durability.
After adding all beads, secure the thread with knots and trim excess.
Apply E6000 glue to the ends of the leather cord and insert into the clasp. Allow to dry.
Optional: Place a lava stone or desired bead in the clasp's setting with E6000 glue for a finished look.
