Mapping a written pattern so I can see what I'm doing. Not my design, and I don't know whose it is. I think it might be by Anna Richardson. It is worked sideways. My notes said the inner sections were worked 13 (not 3) times. I do not know how the end pieces were formed. Ms. Richardson's seems to show the outside patterns being repeated across the rows.
