A few measurements - the piece of fabric is 60 inches wide, and about 8 ft long.

It is cut along the centre line for 18 inches. The back of the neck is the width of the box pleat, 8 inches. The pleats are sewn down across the back neck and for 10 inches down all 4 edges of the pleats at the back, and 6 inches on the outer pleat, but not along the box pleat at the front, so there is a loose rectangle, 12 inches by 18 inches on each side.

When laid over the shoulders the loose rectangles can be crossed over and there is enough fabric to wrap around when sitting down.
