We searched high and low for this excellent sock yarn. Fine super wash merino is intimately blended with nylon for strength, resilience, color retention and wearability--not to mention washability! One skein makes a generous pair of socks. Saki is also excellent for any light-weight projects, especially skirts! Need we say more? Interchangeable with Merino Mia, Book 47 features both yarns. Have fun!
