Check out our supply of Stonehedge Shepherd's Wool. It's 250 yards to 4 oz, and is really happy at 5 sts/inch on a 7. Yes, it's a light worsted. We knit up Mailin, a pullover by Isabel Kraemer, in 5 skeins and it is lovely.
That is Oban in the cream Cumbria, Mailin in teal Stonehedge, and Kahlua in a beautiful taupe called Meadow of Harrisville Watershed.
