I love this pattern and am so glad I recreated it exactly one year after I made the first. I can now see my bracelet progress when I compare the two bracelets that I made.
Anybody that plans on making this shaped (like I did), know that the two most outer and two middle strings won't be seen I would recommend making your B strings the same colour as the two middle strings so when one of them gets shorter you can do a forward knot in row 2 and switch them around. The most outer strings don't need to me that long, I made mine 1 metre because I didn't consider that they wouldn't make any knots and I ended up with 60cm left over. I hope the tips are helpful.
