How to Finish a Beaded Necklace: Knots, Clasps and Crimps
The beads are on, the pattern is just right, and your child is holding both ends so nothing slides off. Now comes the part that decides whether the necklace lasts a week or a year.
Learning how to finish a beaded necklace comes down to one question. What is the necklace strung on? Stretch cord, waxed cord, beading wire and ready‑made chain each close a different way, and the right finish for one can fail on another. If you are still choosing beads and a pendant, start with our guide on how to make a pendant necklace, then come back here to close it up.
Quick Answer
Finish a beaded necklace to suit the material it is strung on:
- Stretch cord: tie a surgeon's knot, add a tiny dot of jewelry glue if the label allows it, trim, and tuck the knot inside a bead.
- Waxed or cotton cord: tie a sliding knot so the necklace opens over the head and pulls snug, with no clasp needed.
- Beading wire: loop the wire through a clasp with a crimp bead, flatten the crimp with pliers, and trim the tail. An adult does the pliers work.
- Ready‑made chain: it already has a clasp, so slide the pendant on and fasten it.
Whatever the method, give every knot and connection a firm tug before anyone wears it.

Match the finish to the string
Most finishing trouble starts with a mismatch, like a knot tied in wire or a flame held near the wrong cord. Check what the necklace is strung on, then pick the finish.
| Strung on | Best finish | Who does what |
|---|---|---|
| Stretch cord | Surgeon's knot, hidden inside a bead | Kids can tie it; an adult checks the knot and trims |
| Waxed or cotton cord | Sliding knot, or a knot through a clasp | Kids can tie it with practice; an adult cuts the cord |
| Beading wire | Crimp bead and clasp | An adult flattens the crimp and trims the wire |
| Ready‑made chain | Use the clasp already on it | Kids can slide the pendant on and fasten it |
One rule covers all four: leave a little slack. A strand pulled tight makes the beads stand stiffly and strains the closure.
Stretch cord: the surgeon's knot
Stretch cord needs no clasp, since the necklace stretches over the head. The catch is that an ordinary knot slips on slick, stretchy cord, so it needs one extra wrap.
- Stretch the cord gently before you bead, so it sags less later.
- Cross the ends and tie them once, as if starting to tie a shoe, but wrap the end through twice instead of once.
- Tie a second plain knot on top, then pull both ends firmly and evenly to tighten.
- Add a tiny dot of jewelry glue to the knot if the glue's label says it suits stretch cord. Let it dry as the label directs.
- Trim the tails, leaving a short stub rather than cutting flush against the knot.
- Slide the knot inside a neighboring bead with a larger hole, so it is hidden and protected.
Never use a flame on stretch cord; it melts and the knot fails.
Cord: an adjustable sliding knot
A sliding knot is the neatest finish for waxed or cotton cord. Pull the two knots apart and the necklace opens wide enough to go over the head; pull the free ends and it draws snug again. No clasp, no tools.
It is also the finish our Pendant Jewelry Kit uses for its bracelets. The instruction sheet calls it a sliding double fisherman's knot. Here is how to tie it on a necklace:
- Overlap the two ends so they run side by side in opposite directions, with several inches of overlap.
- Take the first end and wrap it twice around the other cord, working back toward the necklace.
- Pass the end back through both wraps and pull it snug. That is one knot.
- Turn the necklace around and repeat with the second end, wrapping it around the first cord.
- Slide the two knots apart and together to check that they move smoothly and hold.
If a cut end starts to fray, tie a small knot at the tip.
How the kit's bracelets close
The kit's bracelet cord is folded in half, and an adult seals the two cut ends together with a lighter, as the instruction sheet directs. The folded end goes through a silver bead and then through the loop on one side of the oval bracelet tray. The cord is fastened there with a cow hitch: the sealed ends pass back through the folded loop and pull tight. After the second side is done the same way, the sliding knot closes the bracelet. The flame step is adult‑only and suits this synthetic cord, never cotton or stretch cord. For the same idea on a thicker cord, see how to finish a paracord bracelet.
A sliding knot also rescues a bracelet that turned out loose; see how to fix a friendship bracelet that is too big.
Beading wire: crimp beads and a clasp
Beading wire is too stiff to knot, so it is finished with a crimp bead, a small soft metal tube squeezed flat to grip the wire. It is the most secure finish for heavier beads. Children can thread everything; an adult does the pliers work.
- Thread a crimp bead onto one end of the wire, then the loop of the clasp.
- Bring the wire tail back through the crimp bead, and through the next bead or two if the holes allow.
- Snug it up, leaving a small loop so the clasp moves freely.
- An adult flattens the crimp firmly with crimping pliers or flat‑nose pliers.
- Tug the clasp. If the wire slides, use a fresh crimp.
- An adult trims the tail close with wire cutters, then repeats everything on the other end with the other half of the clasp.
Match the crimp to the wire using the sizes printed on each package; a crimp too big for the wire will not grip.
Choosing a clasp kids can manage
The right clasp depends on who will open and close it.
- Lobster clasp: a hinged claw opened with a small lever. Secure and common on ready‑made chains, though small fingers may need help.
- Toggle clasp: a bar that slips through a ring. Easy to fasten alone, but it can open if the necklace hangs loose.
- Breakaway clasp: designed to pull apart under strain. It is the safer choice for younger wearers.
The chains in the Pendant Jewelry Kit come with a lobster clasp already attached, so there is nothing to crimp or tie. Your child slides the finished pendant onto the chain and fastens it. If the pendant's loop is too small to slide on, the pendant necklace guide explains how to attach a pendant with a jump ring.
Test it before anyone wears it
A necklace is finished when it passes a quick check. Hold it by both ends, support any pendant, and work through this list:
- Tug every connection. Nothing should shift or slip.
- Run a fingertip along the whole strand. Feel for wire tails, rough crimps or a sharp edge on a clasp.
- Open and close the clasp. If your child cannot work it alone, decide who will.
Repeat the tug test now and then, especially on stretch cord.
Safety at the jewelry table
- Beads, crimps and clasps are small parts and a choking hazard for children under 3. Keep them in a dish or tray, away from toddlers and pets, and sweep the table when you finish. If the bead collection keeps growing, here are some ideas for organizing craft supplies.
- Flames are adult‑only. If a cord end needs sealing, an adult does it, away from anything that can catch.
- An adult handles the pliers and wire cutters, and checks each finished piece for sharp ends.
- Follow the label on any glue, including ventilation and drying time.
- Take necklaces off for sleep, naps, car seats, climbing and rough play. Anything worn around the neck can catch, which is why a breakaway clasp suits younger wearers.
Frequently asked questions
How do you finish a necklace without a clasp?
On stretch cord, tie a surgeon's knot and hide it in a bead. On waxed or cotton cord, tie a sliding knot so the necklace opens over the head and pulls snug. Both need no clasp at all.
What is a crimp bead?
A small, soft metal bead squeezed flat with pliers to grip beading wire, holding it in a loop around the clasp.
Why does my stretch cord knot keep coming undone?
A plain knot slips on stretch cord. Use a surgeon's knot, with an extra wrap on the first tie, pull it tight evenly, and add a dot of jewelry glue if the label says it suits the cord.
Can you use a lighter to seal the end of a cord?
Only on synthetic cord that is made to be sealed that way, and only by an adult. Never use a flame on stretch cord or cotton cord. On those, tie a small knot at the tip to stop fraying.
How do I fix a necklace when the clasp breaks?
On beading wire, an adult cuts the wire just past the old crimp and re‑crimps onto a new clasp, removing a bead if the strand comes up short. On cord, retie the ends with a sliding knot instead.
