I know this isn't the first time I've experienced this frogging frustration, but I struggle to remember exactly which projects left me feeling that way. The joy of binding the projects off seem to overwrite the memory of all those little [and big!] drawbacks, and knowing that is enough to help me feel better about the mistake. All I need to be is a bit more careful next time, and count my stitches often before proceeding to the next big step in the pattern or lack thereof.
Besides, I had a great opportunity wind a nice little cake out of my yarn, and while digging the winder for it I found a second set of size 1 dpns that I didn't even know I owned. If it makes little difference between needle material I might just cast the second sock on and spare myself of second sock syndrome to speed things up.
Tonight might not have to be such a big step backward after all.
