I walk in my neighborhood for my daily exercise. I liked the idea of this vest for visibility http://www.adelineadeline.com/accessories/apparel/lightning-vest.html#.UinlZiLD_cd but thought it was a tad expensive. I made this prototype from one continuous strand (85') of day-glo paracord, looks brighter than the photo. No dangly ends as in the ad. It will be easy to make one using reflective cord if I walk or bike ride in the dark. Tony
