No, I've not been having trouble sleeping, I've been knitting a sock pattern by that name, created by the wonderful Glampyre
This was a fun pattern, and in the course of making these socks I learned to cable without a cable needle (when I lost mine on a car journey - wasn't driving, of course) and to keep a close eye out for dropped stitches when I slipped the wrong bit... Other than dealing with the backwards knitting this necessitated, I found it speeded up the process considerably, though not to the point that I completed them in two nights, as their author did.
Worked in a Fyberspates deliciously soft and cosy space-dyed sock yarn, they will be brilliant for keeping my toes toasty when the weather cools.
The colour changes in the yarn do tend to obscure the lovely cables and twists in this pattern, so I plan to make it again in a plainer yarn in the not too distant future.
I also learned a new-to-me cast off/bind off method as my normal technique was far too tight. So, in one project I learned the figure-of-eight cast-on for circular knitting, how to work a short row heel, and a different way of finishing my knitting. I also gained a great pair of socks!
