for anyone else making it, here is how much string i used. i used 100% cotton string with ~1mm thickness, the bracelet is 15cm plus 5cm ties at either side. for the (in my case orange) base string, about 40-45cm, the orange leading string 7m (although i had about 26cm left at the end), and the white string was 3.5m (with 59cm left). hope this helps! 🙂 (this was my first alpha btw)
