Sweltering summer ahead. Outdoor activities - a visit to the county fair, baseball games, soccer games, gardening, exercising, or for the elderly who often get overheated by the extreme temperatures. These cool ties rest on the neck and help bring down body temperature. Visit http://www.lovequilting.com/shop/accessories/watersorb-crystals/ for Watersorb Crystals. 4 tablespoons of crystals, enough to make 3 ties, for only $2. These are similar to the ties used by our troops deployed in locations of extreme heat. BASIC SKILLS NECESSARY Sewing SIZING / FINISHED MEASUREMENTS 3" x 40"
