This is a pretty basic pattern, it was a little time consuming because I used a yarn that was a wee bit too small. In retrospect I think I would rather have a rib at the bottom instead of a seed stitch because it bulges out a little more than I would like it to. (Also, in this pic I haven’t sewn the buttons on yet, I still need to find some.)
I got a little frustrated with the cables on the neck decrease, I wasn’t sure when to stop cable-ing to make it look consistent and flow well with the decreases.
Anyhow, this is a project that’s been on my to do list for quite a while, I’ll be glad to have a cozy bottle next time it gets cold out.

Update!
I finally got the perfect toggles for this cozy! I got them from SuppliesSundries on Etsy, and I think they’re a great fit!
