Here's a worsted yarn that is almost all cotton but with a bit of polyamide for durability, more fluffiness, and slightly less weight. Colors range from neutral white or gray to several pure hues that are strong but easy on the eyes. Knit a wide assortment of garments for children or adults. It's especially great for soft, cushy hats. The chainette construction gives it a nice elasticity that cotton often lacks.
