@LarissaSel yes, you would have to "collect" the loose strings by knotting them against the diamond to create the finished rounded shape. It's impossible for the current generator to produce a pattern that shows the collected/overlapped strings. There's a video tutorial to show how to knot this pattern on #8489 (which is an alpha, but that was before the generator was updated). More tutorials for triangle ends on #17264 and #27252, and for other shaped bracelets on #23580 and #54602 😊
@LarissaSel if you follow this pattern there will be loose strings. To get the effect like in the photos you need to use the technique you'd usually use for triangle ends. You can search "circle bracelet" on YouTube.
