The Pecos is a continuous loop necklace. Like a roadtrip length varies but they are all mixed media--part crochet/part chain/rosary chain etc.
The Pecos self layers~ layers in different ways depending on how you position the focal stones and charms. Some are designed with clasps and can be wrapped three times.
I suggest that on your road-trip through life, get all tied up in gems at least once and fall in love with the Pecos Neckstring.
The Pecos river originates in the Sangre de Cristo Mountains of New Mexico and flows into Texas where it empties into the Rio Grande. I first crossed it on a road trip home from Marfa, Texas. It is big and majestic.
