@graceberge Ahh, sorry, I'm a bit incorrect! Once you make the edges of the triangle start, you fill in the triangle using the 1-2-1-2 bracelet technique, taking it one row at a time. For the ends, you do the triangle first, then do the triangle edges. Hope this helps, and again, if you need clarification, feel free to ask!
@graceberge Those triangle ends are actually pretty simple! If you are familiar with making a teardrop loop for alphas, you simply just use the same technique that makes the triangles with the end of the bracelet. If you are unfamiliar with it, there's a good tutorial for it by Masha Knots. Just search up "Alpha Teardrop Loop" and use the triangles for the ends of the pattern. To make it multicolored, simply use different colored base strings! I hope this helps, if you need clarification feel free to message!
