This is a very cool pattern. Down the Rabbit-Hole by Purrlescent. The stitches for the right and left sock travel in opposing directions, which can make for some oopsies when alternating knitting on both socks throughout the week. I have to pay attention to which sock I am working on so I make sure that I am working the stitches correctly (there has been some negative knitting on these socks). Its not a difficult pattern, but interesting enough to not be boring.
