This fabulous nudibranch (sea slug) goes by the name Chromodoris magnifica. They are shell-less marine molluscs and clearly every bit as magnificent as their name suggests, within the limits of their approximately 6cm size(!)
It is superwash treated 4ply sock yarn with 75% merino wool for softness and warmth and 25% nylon for enhanced durability. It is suitable for approximately 2-3mm needles. About 84 metres per 20g mini skein.
I do not cake miniskeins.
