When it comes to jewelry, you’re no ninny.

You know rhinestone from cubic zirc from pink diamond. You don’t need to rub your teeth to tell whether pearls are real. But when it comes to determining the supernatural powers of your accessories, well, you’re not only clueless but infinitely optimistic.

You wore friendship bracelets to secure many not-so-secure relationships, Tibetan power beads to heal (and your chi still isn’t balanced). Yes, you’re a sucker. But who can blame you for loving trinkets that cost less than therapy?

The latest material of hope? The Wooloop, a brightly colored, multipurpose woolen thread. Tie the string around your wrist or ankle, wear it in the shower, and watch it turn into a cool, textured, feltlike accessory. What may seem to be just a thick piece of raw, soft wool isn’t — the more it comes in contact with soap and water, the more it gets felted.

There now. Ain’t nobody pullin’ the wool over your eyes.

Available at Vo, 169 Ludlow Street, between Houston and Stanton Streets (212-387-7760).
