@Ashturtle the arrow to the right is a forward knot (f) and the arrow to the left is a backward knot (b). The curvy ones are the forward backward knot (fb) and backward forward knot (bf). The f knot is like the first half of the fb knot but twice and the b knot is like the first half of the bf knot but twice.
Hi I was wondering what the straight arrows meant I know what the curvy ones mean but the bit straight if someone could tell me this I would appreciate it so much!!
