Use of Corriedale Sheep: Thanks to the fine-wool Merino influence, Corriedales yield a soft, all-purpose fleece great for spinning and felting. Their wool has a distinctive crimp, a spinning count in the 50s to 60s, and a staple length of 3.5 to 6 inches. An adult ewe will produce around 10 to 17 pounds of fleece a year. Noted as efficient feed-converters, the breed also provides a high quality carcass and has been used in cross-breeding programs to produce premium lamb.
