Civility Sport ***Sport Dk weight Elemental Affects Civility is not exactly 100% "home grown," Civility uses U. S. Merino fleece and imported silk. The two fibers really play well together hence the name Civility. I have added just enough silk to the fine Merino fleece to produce a yarn that is both luxurious and and strong. 70% Merino Wool 30% Mulberry Silk 4 oz 112 g = 400 yds Gauge: 5 8 sts in with US 5 3 (3. 75mm 3. 25mm) 3 ply worsted spun Handwash in cold water.
