To start, choose your beads, play with different shades, effects (smooth or faceted)...

Cut a nylon thread of about 15cm. String a crimp bead, the earring hook ring, then back through the crimp bead. Bring it towards the earring hook ring and then flatten it with the flat pliers.

Now string the beads. Here we have placed 4 beads of 6mm, one central bead of 8mm, and then again 4 beads of 6mm. Hide the starting thread in the first 2 beads and then cut the excess flush.

Place the butterfly clasp on the earring hook.

String a crimp bead, pass through the clasp ring, then back through the crimp bead. Pass the thread through the last 2 strung beads. 

Pull the thread to tighten the threading and form the bead hoop. Flatten the crimp bead and then cut the remaining thread flush.

Repeat the operation for the second loop.

Your jewel is finished!

Beautiful creation!
