Step 1

<b>Prep Elastic:</b> If using elastic, fold each end over to create a loop and then secure with thread.
Step 2

<b>Prep Jewelry:</b> If present, remove the link of jump rings often used to adjust the necklace's length.
Step 3

<b>Attach Elastic:</b> Open the jump ring using pliers, and then insert the elastic or rubber band. Close again using the pliers. Insert the elastic's other end into the jewelry closure. Give a few stretches to test for security.
Step 4

<b>Options:</b> -For the closure, I used a thin rubber band, which will hide easily under short hair without creating bumps. For those with longer hair, consider sewing velvet or satin ribbon to hide the elastic. -*To know how much elastic to use, measure your head's curcumference with a cloth measuring tape (or trace it with a string and then measure the string against a ruler). Also, measure the necklace. Subtract the head circumference from the length of the jewelry. Whatever is left is how much elastic you need.
