Thread a mixture of beads onto your spool of wire.
Thread on as many of as few as you want. 

Thread on your beads in the following order:
1 full pack of 3mm black round beads
1 full pack of 3mm faceted beads
1 full pack of 4mm black beads
2 full packs of 4mm faceted beads
1 full pack of 4mm black round beads
1 full pack of 3mm faceted beads
1 full pack of 3mm black round beads.

Wrap the end of wire neatly around the bangle base. 
Now alternate between wrapping the wires up and down across the bangle until you have wrapped approx. one 3rd of the bangle. 

As you wrap, bring beads across the front of the bangle. 
Position each bead where you want it as you go.

When you are happy that you’ve added all the beads you’d like, repeat your wire wrapping on the other side of the bangle.
Snip off the wire approx. 2cm from the bangle. Wrap the end tightly around the bangle base, hiding it amongst the wire wrapping.
