I used white nylon cord for the base, which frays quite easily. First, burn the end to keep from fraying. Put one clasp end loop on the nylon cord. Then measure how much cord you will need to go around the target wrist(s) (use your own) in a loop with clasps attached. In other words, you will make a knot in the nylon cord so that the clasps are attached at both ends. Double around the wrist plus around 1/4″ extra should work. Best not to make it too tight. Even though you can use the clasp to put on and take off, if you want, the tighter it is, the harder to do by yourself. Make it too loose, obviously and it falls off. Okay, now that you have the length, cut and burn off the end. Use the burn ONLY on the nylon cord(s). Now B4 adding the other end of the clasp, add what beads you want, using double cord through the bead(s). Then add the bottom clasp end (just one cord) and tie the nylon cord(s) into a tight knot. I clip and burn the ends close and put the knot towards the middle. Then put one end of the clasp under the clip on a clipboard. Take two colors of embrodery thread (do not split) and tie together in a tight knot. Pick one of the colors as your TIE BY. This will produce one solid color on one side of the bracelet and one solid color on the other side. I like this because I can remember to tie right by always using the same color. For the instructions for tying the thread onto the nylon cord, I used this example. After I did the first one, I skipped the making the extensions. Just make it clean.
