How to Match Beads and Accessories

  • Use smaller beads with delicate wire and smaller clasps, spacers, and jump rings.
  • Use medium beads with standard wire and medium-size findings for an everyday bracelet or necklace.
  • Use larger or heavier beads with thicker wire, stronger crimps, and larger findings.
  • For a matching bracelet and necklace set, use the same bead colors and pattern, then adjust the length and clasp size for each piece.
  • Check that the wire fits through the bead holes before starting.

Basic Bracelet or Necklace Tutorial

  1. Measure the finished length. For a bracelet, measure around the wrist and add about 1/2 inch. For a necklace, measure your preferred length and add 6–8 inches for finishing.
  2. Cut the beading wire.
  3. Thread one end through a crimp, through one side of the clasp, and back through the crimp.
  4. Pull the wire snug, leave a small loop, and crimp securely.
  5. String your beads in your chosen pattern.
  6. At the other end, add a crimp and jump ring. Thread the wire back through the crimp and the last few beads, then crimp it securely.
  7. Trim the excess wire and add crimp covers for a neat finish.

These are general recommendations. The best sizes also depend on the bead-hole size, the weight of your design, and how delicate or bold you want the finished piece to look.
