This collection of yarn is technically Aran weight but it's Worsted Spun, meaning that the fibers were combed and spun aligned all in the same direction. The advantages of this is that this yarn doesn't bloom as lofty and can therefore be treated like a worsted weight. It also means that there is less pilling with beautiful drape and stitch definition. It's perfect for cables and lacework will be more open and it will retain blocking better than a fluffier woolen spun yarn. It is 100% Superwash Extrafine Merino., 100g, 166m/181yards.
