A lovely yarn from Araucania called Huasco Sock Zig Zag.  Each skein is 80% superwash merino + 20% nylon and has 437 yards/ 100g.

The yarn is the same as you see for these Arched Armwarmers.  The colorway is, of course, different.

Called Water Lily, this is medium-long stretches of colors in fuchsia and navy and mint primarily with some tonal variations.

Really lovely.
