0.5mm macrame jewelry wire
6mm natural pearls
metal beads of different sizes and shapes
a board and a clamp
A  lighter or candle
A  wire cutters or scissors

This method is quite simple, we will first realize  a series of diagonal knots as in the video below. Then in the center of the necklace we insert metal beads and a pretty natural pearl in the center.

To start, cut 5 wires of about 1.5 meters each. Allow for a good length because you will not be able to make connections during assembly at the risk of having to start all over again!

Start the knots starting at about the  center this will be easier to adjust the length of the necklace.

In this technique, the outer thread will be the weft thread, it passes over the others. Then each thread will make 2 knots on the weft thread. When you want to place beads, you will have to thread them before making the knots.

Make a first series of diagonal knots, then insert a metal bead on the weft thread (it's the one that goes diagonally, the one on which we make the knots with the other threads) then make the knots with the 3 threads.

Before tying the knots with the last thread, thread the small metal beads.  Here we put 1 2mm cube bead, 2 3mm beads, a pendant and again, 2 3mm beads and 1 2mm cube bead. Then block the row of beads by making the 2 knots.

Go back in the opposite diagonal, making knots with the threads.

Then repeat the operation with the beads but this time on the 3rd wire you will thread a 6mm bead. Continue in symmetry...

Then make as many weaves as you want and to finish the necklace, braid the remaining threads by making a 3-strand braid (join the outer threads in pairs and leave the central thread alone).

To give you another visualization of the technique, you can check out the bracelet video.

And there you have it! Beautiful achievement!
