Measure out the wire to your desired length (include 2-3" extra, to make it easier to finish your design).
String the crystals, filigree beads, and spacers onto the beading wire.
Bead Stoppers make it easy to adjust the pattern and length.
Finish one end with a crimp tube, wire protector, and crimp cover, then add a jump ring to the wire protector. New to jewelry-making? See Jewelry Basics 101 (PDF) for step-by-step crimping instructions, and most secure way to open and close jump rings.
For the other end, add your crimp tube and wire protector, but before putting the wire back through the crimp tube, hook your spring clasp to the wire protector. Crimp and add crimp cover.
