I did the XXL exactly as written until the underarms.
I used almost 3 full skeins of Wollmeise 100% (NIP). There is a slight color difference in 2 skeins, the 3th one was very different (more red, even a bit green over the gold). I switched to knitting every other row with 2 skeins on the botton half of the cardigan. I don’t think it shows in the final outcome. Or, maybe it does, but it does not bother me.
Very happy with the outcome. I could have done maybe a smaller size for a closefitting cardigan, but I like my sweaters oversized …
I have found the perfect buttons for it! It really needs the ‘just right’ buttons to be finished and wearable. And DH was in the right mood to take pictures, that helped too…
