@AvaDaAlien I would look for a tutorial on YouTube (search for how to make a friendship bracelet). But basically each of the different arrows are knots and the lines are the strings. Good Luck!
This is a spinoff 3 color version of my other pattern, #23837(two colored). Feel free to make color variations (I will make a black and white one and a few others however) Thanks for checking out my pattern and reading this comment! 🙂 LunarUni
