If I understood correctly, I think they may be double triangle ends. In Alex's Innovations starts and ends video she shows you how to make them. Hope that helped 🙂
@1aesthetic if you r worries how long it is after you make the whole pattern double the pattern in the bracelet and cut it off when u want! Hope this helps
This is an alpha pattern. Alpha patterns work different than normal patterns. To learn how I recommend MashaKnots' video on the flat alpha technique. For this pattern you need 9 base strings (colour doesn't matter) and strings in four different colours as the leading strings. @julinha
