I love the look of delicate necklaces layered together like Jennifer Aniston or Lea Michele wear. It's a timeless look and you can easily tailor it to your own tastes.
Just grab an assortment of delicate chains and begin to add charms that suit you. I found some tiny charms at Beads and Charms online and put together a little combo inspired by Jennifer Aniston. Look around and see what you already have lying around! Most craft stores have tons of charms to choose from.
Look for charms that have meaning to you, like potential represented by an acorn, a dream in a wishbone, or the luck a ladybug represents, the solution to a problem signified by a key...
What charms would you layer?
