To make a standard 7" adult bracelet, you will need around 100-140 flat clay beads per bracelet, depending on the thickness of each clay bead (you will notice that some are thinner-cut than others). If you are weighing out the number of beads, you will need around 5 grams of clay beads per bracelet. If you include any additional letter beads, spacers, or decorative beads, you will need fewer clay beads.
