Cord is an alternative to chain: lighter, warmer and available in many colors. It can hold a pendant or be the necklace itself.

## Materials

[Leather](https://www.711grados.com/en/leather/), cotton, silk, nylon or waxed leather. See [rope and cord](https://www.711grados.com/en/rope-and-cord/) for their properties.

## Clasps

- **Sliding knot:** adjustable, with no metal clasp.
- **End caps with clasp:** with caps and lobster clasp.
- **Fixed knot:** one size.

## Thickness and pendant

Choose a thickness suited to the weight of the pendant: 1-2 mm for light pendants and 3 mm or more for heavy pieces. Make sure the pendant's bail lets the cord pass easily.

## Care

Cords wear with sweat and water. Replace them when they fray.
