@erincostaa tysm and I think it's probably embroidery floss or specific friendship bracelet string, but I'm pretty sure they're basically the same thing
Hey, so if anyone sees this or is going to do this pattern, as you can see in the photo I put up there, the pattern isn't meant to have loose strings hanging out. You just have to pull tight and not leave strings out in order to get to how the pattern is supposed to look. By all means, you can do whatever you want with this pattern. My friend made up this pattern and I recreated it, so I just wanted to put it on a website. Have a great day 😊
