Start off by braiding your embroidery floss. You can do whichever style of braid or design that you like, and you can add additional elements like beads or feathers, as desired.
Make sure that the length of each piece of the embroidery floss is about 1 1/2 times the desired length of the final necklace. Securely knot the ends, and add a necklace clasp, if using.
Fill the tiny glass jar with glitter (or your chosen alternative). A little funnel or straw can be helpful with this step. You can simply pop the cork back into the jar, but I decided to secure it in place with a dab of hot glue.
