@frtlmrtl5 because knot 2 in row 1 is f and not fb, when the pattern repeats the red string moved into the spot of the black one on the right side. The people who have made this pattern just don't include the forward knot in their creation, so the colors all stay in straight lines.
So , I am seriously confused…… Two different patterns, but only one set of directions. ??? None of the pics even show triangle part. Wasted my time jumping right in, only to realize it is not a complete pattern. Why is it even here?
