Your choice: the onion sweater
This big pattern looks like a big braid from afar but reminds of an onion with a closer view. We found it in vintage knitwear magazines in 2016 and loved it at first sight. The onion sweater is perfect for you if you are searching for a voluminous wool sweater with a large pattern and a round collar.
Besides, you can have a look at the new V-neck onion sweater of 2020.
