@dqneef i think i finally figured it out! so you see how line 1 and line 15 have a row of backward/forward or forward/backward knots? you will can do the diagonal/candy stripe method in one direction and once you get halfway through to line 15 do the diagonal/candy stripe in the opposite direction... and so on and so forth.

@dqneef try doing it like a candy stripe. i tried doing it row by row once and it came out so wavy. i'm going to try the candy stripe method and hopefully it will come out straighter

@emwest do you mean a loop? Empatheo on YouTube has tutorials how to make different loops with odd colors of string. There's also a video tutorial on pattern #31230 on how to make a simple slanted end.
