@KuteKat I did triangle ends. String length (for any bracelet, really) is usually a full wingspan (fingertip to fingertip) plus a few extra centimeters (no less than 8-10cm). If the pattern is much thicker, I make it a point to add even more. Hope this helps. 🙂
I really liked making this pattern but I think that it would've looked a bit better if I did more of a rainbow or single-colour gradient (I did 3 seperate gradients if you look at my picture)
