How to braid cornrows

Brush the hair.

Using a small toothed comb, separate hair into 8 sections.

Start with one section, gather a small amount of hair and separate it into 3 pieces.

Take the pink (left) strand and cross in UNDERNEATH the blue (middle) strand.

Then take the green (right) strand and cross it under the pink (middle) strand.

Now gather a small section of hair and add it to the blue (left) strand.

Then take the blue strand and cross it underneath the green (middle) strand.

Next, gather a small section of hair and add it to the pink (right) strand.

Now cross it under the blue (middle) strand.

Continue steps 6-9 until you reach a point where there is no more hair left in the section to add into the braid.

Now regular braid as was done at the beginning of this braid.

When the braid is as small as it can go, take a small rubberband and wrap it as many times as needed around the braid.

Repeat steps 3-12 for all 8 sections.

Another option is to only braid 3 sections and end them early to create a look like this:
