Abstract: Historically, when yarn is bought in the form of skeins, the skein would be unraveled and rewound, either mechanically or by hand, into a ball to prevent tangling. The Yarn Wheel alleviates this need by standing the skein on end such that the yarn may be pulled directly from the middle of the skein as the skein is designed to be used. The Yarn Wheel also eases yarn management when doing multi-color work by simply allowing the user to turn the deck and/or reposition skeins as needed. The Yarn Wheel keeps the several different colors of yarn off of the floor, and the height adjustment keeps the yarn always within easy reach whether the user prefers to work low to the floor, on the sofa or at a work table.
