The Re-Tweed is listed as aran weight, but feels more like worsted to me, so I’m using the 6.5 mm hook and starting with a chain of 14.

I decided to use a third color as an accent, switching to Vineyard Wine for the simple stitch button band. I continued in this color for the single crochet edging.

I finally found suitable buttons at Hobby Lobby in Bangor, and for 99 cents.
