CHIEKO crocheted the fabric for this 3x5 inches bow tie. Her work is so tight and precise, it makes my head spin. The yarn is a fine wool and the knit fabric is backed by a stiff cotton to hold the shape integrity. These ties are the most time consuming of all the ties my mother makes (probably alongside the hand-embroidered ones); this is why they are priced as they are. Bring Preppy to a whole new level!
