I've recently purchase Grant's encyclopedia of braiding and on pages 134-136 there is a diagram of a pineapple knot with a skeleton of a 6x7 turkshead. I get the 6x7 and the first interweave done but when I try to do the second interweave, the diagram and my knot don't resemble one another. I'm at my wit's end as to how to finish this knot...any suggestions?
