Cut 80cm of chain. Weave the Elasticity through each link of the chain. Join the ends of the chain with a jump ring. Pull the Elasticity tight to gather up the chain and tie a few tight knots. Trim the excess Elasticity.
Thread a bead onto a headpin, trim 1cm above the bead bend into a loop but don’t close it yet.
Attach the beaded headpin to one of the links of chain. Close the loop. Repeat for all of your beads. Add the bird charms to the chain with a jump ring. Make sure they are spaced evenly.
