@lola122 start with a half triangle end with twisted ties or braids. I don’t recommend using a loop for this pattern. YouTube and TikTok have great tutorials for understanding triangle ends. Hope this helps.
@RyanMarieS in this pattern you don't need to do anything special. You just do all the knots that it tells you to do and leave out the ones that it tells you not to do. The grid effect will be created automatically.
