B.Y.O.S. (Bring your own straw) is easy with this free straw saver pattern. Show your true colors and keep straws clean and handy in a purse or pocket. Carry spares for friends in need! They make great stocking stuffers! Knitted from the cotton that we love for dish cloths, it will absorb stray liquid and can be washed, dried and back on the road with you.
