@fire31 Practice makes perfect 🙂. However, i know that there's a technique on how to keep your edges straight. On the left edge of your bracelet, you make BF knots. On the right edge of your bracelet you make FB knots. Masha Knots made a really good video explaining how to use this technique. Just type in "Masha Knots straight edges technique" and it should pop up.
@karsynrae You should cut 1 string of your wave color at a wingspan length, 1 string half of that as well for your wave color, and 2 strings of your background color at a wingspan length and 1 string half of that as well for your background color. Sorry if that was confusing, that was probably not the best description 😉
