0.5mm macramé jewelry thread
 4mm beads
 a metal bead
 a board and a clamp
 a lighter or a candle
 a thread cutter or scissors

This method is quite simple; we will first make a buttonhole in which the metal bead will lock. A clasp integrated into the bracelet structure, so you can put it on easily and without difficulty!

Cut 2 threads about 2 meters each. Allow a good length because you won't be able to make joins during assembly without risking having to start all over!

Fold the threads to visualize the center, then fix them on the board at the center with a clamp. Here we used a foam board, but you can use cardboard, a plastic board...

Start the buttonhole... then close the loop with 2 flat square knots.

Next, make the bracelet; the outer thread on the right is placed diagonally over the other 3 threads. Each of these will make 2 knots on the weft thread. For the third thread, you just need to string a bead before making the 2 knots.

And there you go! Beautiful work!
