I have made this pattern once before. I used wingspan length plus a little bit more (about 5.75 ft.) but for the darkest color, or outline string, make it a little longer, about a foot. I had to add more in which isn't a huge deal, but it was annoying to see my whole bracelet and not be able to knot all the way through!
I started making one but I didn't know how long the strings needed to be so I just did something. Now I have one 'X' but my strings are too short to do another one. Now here comes my question: how long do your strings need to be? ❤️
I finished it and then ran out of strings to close it off so I bought all the strings to the center as a chevron I put a pic of mine above let me know how you like ( click on the picture, u can’t see the whole thing)
