The String Method

1. Grab anything long and flexible—string, ribbon, shoelace, or whatever you’ve got lying around. Wrap it around your wrist just above the wrist bone, palm up. It should hug, not strangle. Yes, really, go ahead.
2. Mark where the ends meet with a pen or marker.
   
3. Lay it flat, measure to the mark, and voila. That’s your wrist size. Use it to find your perfect bracelet fit.
