The Bellows Cardigan
I had a hard time deciding on a size. The second smallest size had 5″ ease but since I wanted to wear it more as a jacket I wanted a bit more ease than that. The third size up had 10.5″ of ease which is a lot, but in the end I went with the third size and it's perfect.
I blocked the sweater about 2" longer than the measurements called for which took some of the width out from going up so many sizes. Very happy with this decision as well.
The buttons I purchased from Soutache here in Chicago. I went with a large leather woven button on the front and anchored them to smaller buttons at the back of the button band. This prevents the button from stressing the particular stitch you sewed it to if you were just attaching the button straight to the button band.
