I love love love the colorways of Blue Heron yarns and now that they carry sock weight yarn again I can indulge in the glory of their particular rainbow.
This is called Sock Plus and is 420 yard to the slightly more than 100 gram (roughly 3.5 ounce) skein with 80% superwash merino/20% nylon. The suggested needle size (US) is 2-5.
The colorway here is called Indigo Nights and is a tone-on-tone play of teals, both from a light to a deep rich mallard.
Rich and vibrant.
Perfect for socks, of course, or scarves or shawls or anything else calling for a special fingering weight yarn.
A melody all in itself.
