Cut a double arm span of thread and thread on 12 seed beads to the centre. Pass your needle back through the beads again (starting from the first bead you added) and then to through the next seed bead to make a loop. 

Now attach a needle to the other thread too. Thread on a seed bead onto both of the threads.Now thread on three seed beads on either side.

To start your pattern on BOTH sides, pass the needles through a half tile, orion bead, half tile, orion bead until you have used 19 half tile beads (if you want to make a 7 inch bracelet). 

Thread on three seed beads to both sides. Pass both needles through one seed bead. On one strand, add 5 seed beads, your clasp then 6 more seed beads. Pass the needle through the single seed bead you just added.

Now weave the threads back through the half tile and continue to mirror the design on either side. To fill in the gaps with seed beads, string on 3 seed beads on both sides after exiting a half tile. The pass the needle through the next half tile. Continue along the bracelet until you reach the end.

Weave your threads through the design to reinforce it, tieing a few half-hitch knots along the way. Once you are happy that your design is secure, trim away the tail threads.
