Yes, all the strings are from are from a flamenco guitar set. They are not ball end- just tired with a figure eight knot. The hole they terminate in is a keyhole so they lock in firmly. The sides mimic the back in that they are more figured near the tail and curl near the head.
sooooooooooo, two nylon strings and one wound? Are they all ball end? That's what it looks like. From this photo, I think that your sides are not the same all around? Beautiful workmanship. aloha, irene
