You will need bead tips - you take a bead tip and run a long piece of cord through the bottom of the tip and tie a knot in it . Then take a split ring and close the bead tip around it. open the split ring and attach your clasp. It sounds hard but to see it done is very easy. I hope I did not confuse you or you can just tie a knot in it after you have all your beads on it . It will stretch..
