3 eye pins 60mm 
 from the 5mm Oval Link chain
 6 beads 6mm
 14 beads 4mm
 2 polygon beads
 5 Heishi washers in Brass
 a lobster clasp
 2 rings 4mm

To start, string the beads onto the pins and form the loops using round-nose pliers.

See the technique here: Form a loop

Here we placed 6 beads 6mm interspersed with metal washers.

Then 2 pins with 7 beads 4mm and 2 metal beads at the ends.

Then bend the pins so they better fit your wrist. 

Next, open the loops to connect the pins together.

You can see that the bracelet is articulated and takes the shape of the wrist.

Next, measure your wrist and the size of the bead pins.

Then cut a piece of chain long enough to make a second wrist wrap.

Cut this chain into 2 pieces.

Attach the chain to one side of the beads then connect the chains to the cowries with 4mm rings.

To finish, place the lobster clasp on the other side of the bracelet.

And there you go! Beautiful creation!
