@EmaD30 there are four knot types in friendship bracelets: forwards knot ↘ (f) backwards knot ↙ (b) forwards backwards knot ↩ (fb) backwards forwards knot ↪ (bf)
All knots consist of two halves. For the f knot you take the left string and knot with it over the right string two times to the right. For the b knot you take the string on the right and knot with it over the left string two times to the left For the fb knot you take the left string and knot with it over the right string one time to the right and one time to the left. For the bf knot you take the string on the right and knot with it over the left string one time to the left and one time to the right.
