Finished up a beer cozy last night. It took me 4 or 5 starts on Friday while waiting at a coffee shop before dinner before I finally got the start and the increases down to the point where I felt comfortable with it. This was practice with the DPNs for me before I start on a sock pattern.
It ended up being a little loose - the woman at the LYS had recommended I not knit it too tightly based on her own experience with these, and since I tend to knit tightly by default, I backed off some. The next one will be a bit tighter, and I'll make sure to measure it pulled up a bit instead of slack (as it also ended up a little longer than I'd have liked).
But, that said, I'm happy with how it turned out, and it was a good, small (fast!) learning experience.
