Pick how many beads you would like in a cluster, we used 6 or 7.
Thread these beads onto headpins, then trim and loop them.

Next, loop the small bead charms onto your chain in evenly spaced sections, leaving 2 balls inbetween each cluster (see image) keeping all the beads inbetween two balls on the chain.

Repeat until you have 5 clusters with one at the centre.
