from the heart chain
a lobster clasp and extension chain
of the  3mm rings
6mm connector and 4mm pendant settings

Ultra simple assembly:

Start by measuring your wrist, then subtract the value of the crimped connector. Divide the value by 2 to get the measurement of the chains.

Cut the 2 pieces of chain. If your measurement does not fall perfectly with the positioning of the hearts, reduce the length of one heart, the extension chain will complete the size of the bracelet.

Then connect the chains on each side of the connector crimped with 3mm rings.

Finally, cut a piece of about 3cm of extension chain, then connect it with a 3mm jump ring at one end of the bracelet. To finish the bracelet nicely, place a small setting at the end of the extension chain.

On the other side, place the clasp with a 3mm ring.

And there you have it! Beautiful creation!
