As you already understood, you will need beads of any color and a satin ribbon (rather thin, about six millimeters). Of course, you can take a wider ribbon, but then the amount of beads will increase, it will need to be selected by eye. You can weave a bracelet both on a fishing line, and on monofilament or a strong thread. It all depends on your preferences, it is more convenient for me to weave such light bracelets on kapron thread.
Have you prepared the beads, ribbon and needle with thread? Then start weaving a simple bead chain (weaves on two strands). String ten beads on the thread, pass the last end of the thread through the last three beads, close the thread in the ring, now string two beads on one thread, five on the other, and pass the first thread through the last three beads on the second thread. Get a second ring, in this way weave a chain of the required length.
When the chain is ready, just weave a ribbon of the required length into it (so that its ends can easily be tied around your wrist). Bracelet "Simple" from beads and ribbons is ready! Now you can move on to mastering more sophisticated beadwork techniques. Good luck
