Drop beads
Metal beads
Decorative chain
Extension chain
A lobster clasp
Oval rings 3x4mm
Flexible brass wire 0.4mm

To start, cut a flexible brass wire of about 10cm. 

Then, string 7 drop beads alternating with 6 metal bicone beads.

For a small wrist between 15cm and 17cm, cut 2 pieces of decorative chain of 4.5cm each (i.e., 4 decorative links).

For a wrist between 17cm and 19cm, add a decorative link on each side.

Note, the extension chain will allow you to perfectly adjust the bracelet to your size.

Connect the bead strand to the chain:

Form a small loop with round-nose pliers about 3cm from the end of the brass wire. Insert the chain into the brass wire so it sits in the created loop.

The smaller your loop (while keeping enough room for the chain's mobility), the more discreet and harmonious your assembly will be. The goal is to forget the fastening method to highlight the bead strand and the continuity with the chain.

Then, with flat pliers, hold the loop so it stays well closed and in shape. Then wrap the brass wire at the base of the loop making 3 tight turns. Cut the excess wire flush and tuck it in with flat pliers to prevent snagging.

Do the same with the other end of the brass wire and the other end of the chain.

For added comfort, slightly twist the bead strand to give it a curved shape that will follow the wrist.

To finish, cut an extension chain of about 3cm then connect it to the chain with an oval ring.

On the other side, connect the lobster clasp with an oval ring.

And Voilà! Beautiful creation!
