In these variations on the previous patterns (see here and here) I have played with several colors on the left and right and with different widths. The fourth pattern makes clear you can use a thread of a totally different color at the sides when it doesn’t show up like a knot anywhere. Take notice also of the sides of the previous purple and yellow variety!
Do you see that the thread on the side isn’t becoming visible as a knot anywhere? This gives more possibilities.
