Comprised of an interesting blend of milk and soy protein, this yarn is as unique as it is beautiful. With a wonderfully silky texture, this yarn will gently glide through your fingers while knitting. The resulting fabric will have the delicate body, drape, and shine of silk as well, but with the crisp stitch definition more often found in cotton. Give your next shawl, scarf, or summer sweater an added beauty and let this clever yarn make your stitches shine. Care Instructions. Hand wash, lay flat to dry.
