@gracie_ram If you’re talking about the triangle end, then Masha Knots has a triangle end tutorial on YouTube. If you’re talking about the square knot though, Kinsey B has a keychain tutorial and at the end she shows how to do a square knot.
Lovelt pattern! Think I will try to make ik for the weekly challenge. Tip: I would make the 10th knot on row 23 a forward knot (in the basic pattern a black knot).
