Leading Men Show Stopper: Intermission Show Stopper is the perfect sock yarn. It has your basic composition of sock yarn with Superwash Merino and Nylon, but there is nothing basic about it! This base is so soft you won’t be able to not have it next to your skin. Intermission is the halfway point in a performance. This half skein of Show Stopper is just that: halfway to a full skein.
