"Moonlight" Echo self-striping bfl from Fyberspates.
This was a surprise! After the mice ate my stashed Echo yarn, I unexpectedly received a further installment of the Fyberspates sock club - even though I had already had my full quota!
I suggested to Jen that the mice had clubbed together to buy me this skein, but in fact it was a simple administrative error. Shame - I liked the idea of guilty yarn-munching rodents pooling their pennies to repay me!
I am definitely not short of sock yarn at the moment. MUST. KNIT. SOCKS.
