The swifts are made from Italian grown beech hardwood and last a lifetime! Hold your hanks on the swift while you wind them into balls. Clamp onto table or counter tops. Easy loading is possible if you start with the umbrella in the down position. Put the open loop of the hank over the swift and pull it lightly so the far side of the hank is against the center of the umbrella section and you are holding the hank out perpendicular to the swift. Then, use your free hand to slide up the umbrella clamp, opening the umbrella to the circumference of the hank. Secure the clamp in place and wind away. Measures approx. 26" in diameter (68" circumference) and 26" tall when open.
