This brand new LARGE size yarn swift is made of birch with a fine finish by sanding. The large size can hold skeins up to 8.5-ft in circumference. It spins smoothly and makes yarn winding a fun job. The clamp-on base allows it to be firmly fixed at the edge of tables, chairs, benches, or any convenient locations up to 1 3/4 inches thick. The craftsmanship on these swifts is superior. We avoid wood pieces with scars or blemishes so that our yarn swifts are less vulnerable to breakage and more appealing aesthetically. The ends of metal tying wires are hidden into holes and will never hurt your hands or the yarn.
