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.
