The SKEINO Harlequin yarn is made using Extra Fine Merino Yarn of 19.5 micron. Each fiber is almost as fine as Cashmere (15.5 microns) and can be considered similar in look and feel. A Harlequin yarn ball contains 600 yards of worsted weight single spun yarn with a long and random color repeat, 7 oz. (200 grams). While knitting this yarn, you can watch the randomly changing colorway, self striping.
