I made an "
Endless" necklace today without a clasp. Here is how. (I have modified these instructions recently to improve the technique.)
1. Make a large loose knot (which will eventually be cut off) and place a
spring type bead stopper on the thread so as to leave a 3 inch gap between the knot and the pearls you will string on. (Technically you don't need the knot but it provides a bit of extra security if the spring bead stopper releases accidentally.)
[Purpose of the long tail: You will need to grasp this thread "tail" later when finishing the strand, and can later pick the large loose knot apart, string the tail onto a needle, and pass the tail back through the previous pearl to conceal the cut off end.]
2. String on the
last 3 pearls from one end of the necklace and the
first 3 pearls from the other end of the necklace
without knotting between them. (i.e. the order is 3rd pearl from the end, 2nd from the end, end pearl, then continue with pearls from the other end of the strand with end pearl, 2nd pearl from the end, 3rd pearl from the end).
Using pearls from both ends of the strand ensures that the knots you make later between them are balanced across the back of the necklace on your neck.
3. After the 6th pearl make a knot. String on all the rest of your pearls, knotting as you go.
For a very long strand I recommend using the technique described starting at post #34, as it avoids the tangling of a very long thread.)
String on the final pearl and make a knot.
Now you are ready to connect the two ends of the strand so they form one continuous circle.
4. Insert the needle back through the
first pearl (entering from the side where the bead stopper is). Pull the needle and thread through the pearl, snugging up the thread by pulling the "tail" with one hand and the needle with the other hand, in opposite directions. The knot you made after the
last pearl serves as the knot separating the last pearl and the first pearl.
Do not cut off the tail yet!
5. While maintaining the tension keeping the two ends of the necklace together, make a knot between the 1st and 2nd pearls, then pass the needle through the 2nd pearl.
Make a knot between the 2nd and 3rd pearls, then between the 3rd and 4th pearls, between the 4th and 5th and between the 5th and 6th. (That is 5 knots to ensure the necklace doesn't come apart. More knots = more security without needing to apply glue. If you don't want that many knots, then string fewer pearls on initially.)
6. To conceal the end of the thread before trimming it off, pass the needle through one more pearl and cut it off without making a knot. (I like to use a Thread Zap for this as it melts the end of synthetic threads so they don't fray. Do not use Thread Zap on silk-- it chars the thread.)
7. Now go back and trim off the original large loose knot with its tail of thread, close to the first pearl. Or, if you want to conceal the cut off end, pick the large knot apart, thread the tail onto a needle, and pass it back through the previous pearl, then cut it off without making a knot. If it's too tight, you can use just one of the threads of the tail to do this, and trim the other one.
Edit: I found a video on YouTube that shows a slight variation of this:
If you use the method in the video, DO use a bit of glue on the final knots.
One more addition: For those who want to restring a necklace long enough to slip over their heads but not long enough to be doubled, but who prefer to connect to a clasp rather than attempt an endless necklace, a solution is to attach your gimp to an infinity connector (a.k.a."infinity component"), or any connector that has loops large enough to thread your gimp through. (That's assuming you want to use gimp at all. You could also just attach your thread directly to the loops of a connector.)
You could also wire wrap any bead to serve as the connector, for a necklace long enough to slip over your head. Put a piece of wire through the bead and make a wrapped loop on either side. Connect your thread to this bead instead of a clasp.
It occurs to me that you could also use this method to place a wire-wrapped focal bead in the front of the necklace.
