@Alrak25 I just consider this a gap bracelet. Chain bracelet might be the term you are looking for.
To make this bracelet, just follow the pattern exactly as shown. If you want the colored strings in between to be longer, just do as many fb knots as you want followed by a forward knot like in the pattern. Be sure to count how many knots you do so you can make all the strings even.
