@BeadGirl16 the white strings definitely get used the most. I think I used 96 in (8 feet) of my color changing thread but one of those strings ended up too short because of the way I knotted the loop. So if you plan on knotting the loop, I would make the white strings maybe a little over 8 feet, the black strings 7 feet, and the rest 6 feet.
@sab_sunday ok thanks! BTW how long did you cut your strings? I usually cut mine about six feet, but it looks like the black and white get used more than the others, so I don’t know how long to cut them.
