Crimps
Crimp beads are used when stringing a beaded piece (like a bracelet or necklace), which has been strung with beading wire. The crimp beads finish the end of the beaded piece of jewelry and help create a loop for the clasp to be attached to. Once in place, crimp beads are crushed with a crimping pliers to seal the connection.
Crimp covers are ingenious little items designed to be closed around a crimp bead after crushing. When closed properly, a crimp cover looks like a bead that is part of your design!
