Gather your materials.
Fold all 2-yard pieces in half. Keep one trim separate (for us, it's 10628-BK).
Twist the pearl trims by holding the cluster in each hand and turning the ends in opposite directions.
To measure the size of your necklace-to-be, carefully wrap the strands around your neck, firmly gripping it in the front. Be sure you can slide the pearls up over your head.
Remove and begin wrapping the set-aside trim around the area you were pinching closed in your hand.
Wrap six times and tie a knot, threading the end through the other pearls to make sure it stays.
Try it on, and don't forget to tell everyone who made it!
