Unicorn's Small Umbrella Swift helps to transform skeins into balls with super efficiency and reliability. Clamp it onto a table along with (or without!) your ball winder and watch the magic! It's quick, easy and fun and gets you right on your way. Now, if only there were a gauge swatch making machine... Closed, this swift's circumference is 12 inches; open, it is 72 inches; either way, it is 22 inches tall.
