In Kumihimo interlacement occurs at the Point of Braiding where the various braiding strands come together to form the braid.
In using the takadai or baby takadai interlacement occurs when a yarn is moved through a group of yarns by going over and under them — for instance: over 1 under 1, over 2 under 3, and so on. Braids are typically oblique interlaced structures which distinguishes a braided structure vs. a woven one.
Pictured to the right is a woven interlacement.
