25 meter skein of Appleton wool made of 2 indivisible plies. Appleton Crewel wools have been produced in England from 150 years. They have been also used by William Morris for creating his best-known rugs. They are really appreciated for their colors. Since they are wash-proof, they are ideal for all types of needlepoint and rugs. Appleton wool is the most suitable thread for embroidery since it is spun with Norfolk long-haired sheep wools.
