Cut a piece of thread approx. 1 arm span long. 
Thread through the sieve so you can knot it on the underside.

Create the outer petals using size 11 seed beads. Each petal has 15 beads. 
Go up through a hole, add the seeds and go down through the next hole. 
Continue adding petals around the outer edge of the sieve, then knot off the cord on the underside.

Cut another arm span of thread and repeat the last steps using 25 size 15 seed beads for each petal.

Create the centre by first covering the middle with the size 11 seed beads keeping them close together.
Next, fill in any gaps using the size 15 seed beads.
Knot the cord on the underside once it is complete. 

Thread your pendant on to your chain. 
You may need to remove the clasp on the chain to fit it through.
Finally attach the clasp again.
