I made about 4 different designs and I will post all the materials I used. They are constructed in the same manner with a bit of length changes due to the length of the connector and the pattern of beads. I am also using the crimp beads specially designed to work with Elasticity.
I am using Cxech glass pearl strands, but a variety of beads can be used. I first started stringing my beads on to the elasticity directly on the spool. I used a simple pattern of a 6mm pearl, 8mm pearl in black and silver grey respectfully. (Tip) if you have a problem getting through the pearl, use a head pin to ream or clear the hole.
You want elastic bracelets to fit a bit snug, so in the case of the heart connector (42mm) I strung about 6 1/2" of pearls ending with a 6mm.
Add a crimp bead to the end of the elasticity and then run the end through the loop of the connector, stretching the elasticity, run it back through the crimp bead.
Using chain nose pliers, flat crimp the crimp bead and trim the excess close to the crimp with nipper tool.
Cut the beaded portion from the spool with a few inches to spare or enough to stretch so you can add the crimp bead.
Add the crimp bead, run it through the loop of the connector, stretching the elasticity to get it to go back through the crimp, crimping as above and trim to complete the piece.
The following color combinations were used in my samples:
