It’s done! Well, mostly done. The buttonholes still need a bit more work before they go into heavy-duty use, but they’re in at least.
It’s not perfect by any means, but it’ll be wearable and (hopefully) warm. You can find all the nitty-gritty details on my blog here, and the flickr slideshow here. The pattern, once again, is Butterick 5425.
This is my first winter coat, and it was a very, very long road. I want to thank everyone here for their tips and suggestions, as well as their own posts that I learned so much from!
