Me, I suffer from Second Sock Syndrome (2nd anything, really), but luckily there are ways to work around that - 2 socks on 2 circulars or even 2 socks on 1 circ (my preferred method).
Then there was Nutkin, cute, but ultimately boring. Never knit its brother.
Then Platypus - I never got past the toes (which is bad in a toe-up).
Recently, the German pattern Treppenviertel has piqued my interest, and all bad experiences aside, I decided to give them a try. Not because I needed or even wanted a pair of socks, but because the pattern looked interesting enough to knit them despite being socks. Might not even wear them, but I swore to myself that I'll finish them.
