Abstract
A fabric strap may be configured to attach an electronic device to a user's body. Some of the strands in the fabric strap may be stretchable strands. A stretchable strand may include an elastic core covered by one or more layers of material. The elastic core may be formed from a single elastic strand or may be formed from multiple elastic strands. The first layer of material on the elastic core may be a strand that is twisted around the elastic core. The second layer of material on the elastic core may be a strand that is braided around the first layer of material and the elastic core. The first layer may have a thickness that is greater than that of the elastic core and the second layer of material. The first and second layers of material may be formed from non-stretchable or stretchable materials.
