To create your delicate beaded bracelets, simply cut a length of elastic for each bracelet.
Thread on your beads including your feature bead for the centre of the bracelet.
Double knot your thread and secure with a drop of glue or some clear nail varnish. 
Remember to allow for being able to stretch your bracelet over your hand. 

To create your connector and beaded bracelets, cut two shorter lengths of elastic and knot onto your connector.
Thread your beads onto each side of elastic and knot together.
Trim your thread when you are happy with your bracelets.
