4 ounce bags of Grey Ready-to-Use Wool Roving. Professionally washed and carded by Alford Family Farms and Spinnery, with great care taken to ensure a wonderful end product. The wool is skirted, pre-washed followed by opening, tumbling, hand picking of vegetable matter, two washes, two rinses and carding. The scouring process allows for a gentle moving of water through the wool to avoid agitation. Temperature controls prevent shock to the fleece as it soaks. No harsh chemicals are used in the cleaning of the fleece. A Stonehedge picker and carder process the washed fleece. This GORGEOUS roving is from a grey Shetland fleece. The roving is perfect for spinning and knitting, or felting into warm garments! The carded fiber is super easy to spin on a spinning wheel or drop spindle. The color is a lovely grey. This wool is from the flock at Avon Grove Charter School, PA.
