@Alaa0020 I know it's a bit late, but did you mean how do you know how much string of each colour you need? Because if so, you can't really tell because it depends on the size of your knots, the size of the pattern, how much you leave hanging when attaching new string, etc. In my experience a good rule is that you should always have more than you think! Alphas take a looot of string, it's kind of sad 😭 Feel free to message me if you have any more questions!
