How can three loose strands become one braid?
A braid gathers several flexible strands into a band without melting or gluing them together. In a simple three-strand braid, an outside strand crosses over the middle strand. The other outside strand then crosses over the new middle.
Each crossing changes which strand is in the middle. Repeating the moves makes the strands take winding paths around one another. Contact and friction make it harder for one strand to slide straight out when the braid is held together.
Trace each colored strand through both crossings; a white break marks where another strand passes over it.
The crossing pattern does not make the ends disappear. An unsecured end can unravel as the crossings are undone. A tie, stitch or other fastening can keep the finished arrangement from opening.
Braiding differs from making a yarn by twisting many short fibers along one direction. It arranges already continuous strands in a repeating path. Hair, cords and textile bands can all use this idea: a sequence of local crossings makes a longer organized structure.
About this explanation
Friction, strand material, crossing pattern and end fastening affect real braid strength; this is a flat three-strand example.
Starting knowledge: Follow a repeating sequence and distinguish one strand from another.
