1. I got 1 meter long leather cord and cut it in half. This length fits my wrist nicely but you might want to start your first one with a longer piece to figure out your personal perfect length.
Next you need some sort of colored string and a bead with a large enough hole to fit all endings through.
2. Start folding your leather in an exact half. Tie your colored string around it with a knot to form a nice loop. Wrap around a few times making sure you tuck the endings. Cut off the rest of endings.
Now start weaving in a figure-8 pattern around your two leather cords. Stop a few inches from the end.
3. Again wrap a few times around tightly and secure with a knot. Place a drop of glue onto the knot and cut the string ends.
4. Add the bead and another knot - you're done!
