@avrybow-15 for future bracelets I can give you two hints:
- if you ever run out of string, you can always attach new string. Alex's Innovations has a video on how to replace broken strings in which she explains several different methods
- you can count the knots that each string makes. The first and the last string make 0 knots, the second and third make 3 knots each. First and last make knots in 0% of rows while second and third make knots in 75% of rows. You can see that this is a lot more, which tells you you need longer string.
(I wrote a formula and according to it you need 45cm for the shorter strings and 120cm for the longer strings in this pattern.)
