When I purchased my ball winder to the right, I didn't realize that I needed a swfit to hold the skein of yarn. After surfing the net, I didn't want to pay so much for one. My husband constructed the above swift in 2 hours. The materials cost a total of $14, and it works great. It sure beats using chair legs as a yarn holder and handwinding onto a paper roll. The base sits on rubber shelving material, and an old CD buffers between the arms and the base.
