The foundation: determining the size of the braid.
The size of the cornrows depends on the style. I always recommend that the size of the cornrow is less than half an inch in width. Also it is very important to make the cornrow as flat as possible. Do you know why? Hair weaving, like most art work, only looks as good as its foundation. For a hair weave to look realistic and smooth, it is important to make the cornrow as flat and as close to the scalp as possible.
