@sofie_007 I don't think there is. This pattern can be knotted in a v shape similarly to pattern #2 with two differences: The first knot of the v shape is a fb knot on the left and a bf knot on the right. This will create the white border. The next change is the knot before the knot that connects both halfs. Instead of knotting to the middle like a regular chevron you knot that knot to the outside on both sides.
