@daisyjane Masha knots has a tutorial on triangle ends. But, if you would like to start them in a different part of the pattern just make the triangle ends where you would like to start the pattern. Hope this helps!😊
@Crafty_K it's called einhornwolle (unicorn wool) and is from a chain of cheap stores in Europe called Tedi 😊 I've seen a similar one that I think is called summer nights used by some people on instagram. No idea where they get it thou.
