These scarves are made with ribbon recycled from chiffon skirts and dresses. Each scarf is completely unique. Every one is a different length, weight, texture, and color depending on the ribbon used. The ribbon material is soft and light, making these great accessories for any time of year. The ribbon was purchased from a company who employs and helps to support women in developing countries. In order to most accurately estimate shipping, the heaviest of the scarves was used for calculations. The length measurements were taken in a relaxed, flat position. The length can vary depending on how far the scarf is stretched or relaxed. When ordering, please let me know if there is a particular color family you prefer. Size variants have varying lengths in each: S includes lengths from 40-63 inches; M includes 68-85 inches; L includes 95-112 inches; XL includes 130 and 156 inches.
