This is still from Everyday Fashions, 1909-1920, As Pictured in Sears Catalogs.
By the way, is anyone else fascinated by the sweater coat worn by Margaret in Boardwalk Empire? It's in the second show, it's blue, and it has a garter-stitch knitted belt. Fabulous.
The sweater on the left here is pretty straightforward. It's a version of basketweave.
The one on the right is giving me trouble. It looks like Chevron Stitch, but it's going in the wrong direction. It could be worked sideways, of course, but I don't think so.
It could be a series of 1 x 1 cables.
I don't know. Anyone? Bueller?
