Throughout the holiday season I wore my pearls with a ribbon a lot. Pearls seem dress up any casual outfit just enough to make it fit almost any occasion.
I'm sure you have all seen something similar on Pinterest...but here is another "how to"...
{depending on how the strand is...wrap it 3-4 times}
{pull the ribbon through the two ends so that you have one "loop" and two ends of the ribbon left}
{you can also try to twist them up to give it that extra bulky look}
{tie the ends into a bow and you have a pearl/ribbon necklace}
