This Sprout Sock was dyed exclusively from The Fiber Seed for Mosaic Yarn Studio's 20th Anniversary. Considered a fingering and/or sock weight (same thing), but it is slightly thicker than your average sock yarn. The merino wool is "Superwashed" allowing it to be washing in a washing machine (agitated). It's American made from sheep to finished yarn. Low micron wool worsted spun plys offer a soft smooth handle with durability. The nylon blend aids the wool in durability without making it feel any different than if it were 100% wool. So, with this blend, don't limit yourself to just socks. Sprout Sock is great for shawls, sweaters, hats, gloves, or anything else you can think up.
