4mm cushion beads
 An eye pin
 Fine chain
 2 oval 3mm rings
 A lobster clasp 
 Extension chain

This creation is very easy to make.

The choice of chain will be very important; the finer it is, the more delicate your creation will be.

To start, thread the 3 cushion beads onto an eye pin and form a loop as small as the one already present on the pin.

Next, measure your wrist as well as the bead assembly. Subtract this measurement from your wrist size and divide it by 2. 

Cut 2 pieces of chain to the obtained size.

If needed, widen the chain links with a reamer to facilitate the passage of the rings.

Then connect the bead assembly to the 2 pieces of chain.

Cut a piece of extension chain about 3cm long.

At the ends of the chain, attach the lobster clasp and the extension chain with 3mm rings.

And there you go! Beautiful creation!
