See illustration:
Wire / thread end (B) through a crimp tube (C) and through the eye of a clasp (D); then back through the crimp tube. Pull the loop of the wire so that there is some slack left for the clasp eye. Now, crimp the tube (E). Optimal grip is achieved when one wire end lies to the left and the other to the right of the fold.
To complete the process, firmly squeeze the tube in the front part of the pliers (F) with the fold facing forward. Now, string the beads. Then, follow the previous steps again. Leave some space at the end. The larger the beads, the more space you should leave. Crimp pliers can be found in accessories / tools. Cut the shorter piece of wire flush with the tube. Then, gently pull on the loop so that the cut wire end disappears straight into the crimp tube.
