Basic technique for jewellery making: how to use crimp beads and crimp bead covers?
Attach a clasp on metal wire using a crimp bead. Start by stringing a crimp bead on your metal wire followed by the clasp. Pull the wire once again through the crimp bead in the opposite direction and close it with a special bead crimp tool. Pick up a crimp bead cover with flat nose pliers, place it over the crimp bead and close it carefully.
