Fingering Weight
Cloud and Milky Way are both light fingering yarns.
Cloud, Domino, Dottie, Haiku, Lunaris, Nebula, and Squishy all make great sock yarns.
Dreamy, Gerty, and Luster can also make great sock but will shrink or felt if they accidentally find their way into the washer or dryer.
Dreamy, Gerty, Serenity, Silken, and Squishy can all be used as finger or sport weight yarn.
