Hydrate in style with the help of this hands-free bottle holder that fits most any 16- to 20-ounce bottle. The less-is-more design is easy to duplicate and features a rubber O-ring that costs under a dollar at a hardware store.
To prevent fraying, brush clear nail polish (supervise younger kids) onto both ends of the webbing and allow it to dry.
Feed 2 to 3 inches of the webbing through the O-ring and secure with a dungaree button. (Push the tack through the webbing, place the button on the point, and press firmly together.)
Repeat for the other end of the webbing. Be careful not to twist it before you attach the second button. Decorate the strap if you like. Slip the O-ring over the neck of the water bottle.
