This yarn is a single ply blend of extrafine merino and silk. It has been hand dyed so there will be some variation between skeins even within the same dyelot. For larger projects it is recommended that you stripe different skeins together to blend them together. This yarn is very soft, with a slight halo. It feels slightly finer than a standard 4ply, it can be knitted to a range of tensions but would probably be at its best knitted slightly looser. Perfect for accessories and light summer garments, it has excellent yardage.
