@jennacarol I would say this probably applies to the outer four strings of a and b, but not so much for the inner two.
According to my calculation (from the outside to the inside): a: 113.75cm b: 110.625cm c: 95cm c: 88.75 b: 70cm a: 66.875cm
In cases like these, where you have multiple strings of one colour but one gets used up a lot faster than the other, you can also switch the position of these two strings by making one fb or bf knot between them instead of one f or b knot when they meet.
so easy to memorize! i’ve made three of these. i love making it so much. cut about 6 1/2 feet of the string, but 7 1/2 for the loop string. eats string up if you aren’t careful. the white is fine, but you may run into problems with the others. i still had excess after making 8 of the squares, so it just depends on your wrist. cutting 7 feet may help depending on the size you need.
