The most common use for this braid is for braiding hair. However, it's also a good way to tie three lengths of rope into a single braided rope for more strength.
1 To start, you'll need three cords. The cords may simply be held together, or you can tie them together at the top. To start braiding, move the left cord to cross over middle cord.
2 Next, take the right cord and cross it over the new middle cord.
3 Continue making crossovers, alternating sides until the braid is as long as you need it to be. Secure the ends, if necessary.
The Three-Strand Braid is sometimes tied with strands of different colors. Moreover, each strand can be a pair of cords, or a group of cords.
