I'm knitting it with Rowan Big Wool (yes, I'm a real yarn snob ... But I enjoy knitting with nice yarn much more, not to speak of wearing the final project.) I decided to go for black and off-white, although I also really like the suggested colourway of black and red. The local yarn shop didn't have any nice red and also I thought since it's a layering piece the more versatile the colours, the better.
I'm really enjoying knitting it so far, although I had some trouble with the lifted increases and at first also with the tubular cast on. On the other hand it's nice to have a bit of a challenge and learn something new. I think it's really obvious that the designer put a lot of thought into the pattern and the shaping of the back looks really beautiful.
Unfortunately, it's not so well visible with the black yarn ... As you can see in the cast-on row, I didn't listen to the author of the book and just bought one size of needles, since the girl in the shop said that it should work fine. So, I didn't use a size smaller needle for the cast-on row and it's a bit loose. Well, it's not perfect, but I'm ok with it.
I like the fact that this vest is so nice and curvy and that it knits up fast. I'm really looking forward to see how it'll turn out!
