Double-bed jacquard (needs ribber)

A Fair Isle image with no floats on the back. The back shows a bird's-eye speckle, stripes or ladder pattern. The fabric is thick and its edges are clean. The main bed knits the card pattern (Fair Isle selection); the ribber knits a backing on its own needle arrangement and its own cam settings.
