MCS is a 75/15/10 blend of Merino, Cashmere and Silk. This is available in a 400 yard skein of fingering weight yarn
This is the best fingering weight yarn I have knit with. It's hard to say how great it is, so you really have to try it for yourself. It is fun to knit because it glides over the needles. With the cashmere and silk, it has a fabulous look and feel. I will be buying more.
