Kestrel is spun from the same superlative organic linen fiber as Sparrow, but its structure and appearance couldn’t be more different. Kestrel is a ribbon yarn, a small knitted tube. It knits up quickly on 6mm needles. We love it in plain stocking stitch and simple silhouettes—the better to show off its texture and drape. When you want quick summer knitting in the lovely linen, use Kestrel.
