FYI, this isn't a "regular" 4 strand braid. The typical 4-strand you would usually see has more of a round shape to it. This is a woven flat braid, something a little bit different. I think this braid is actually much easier to do than the regular 4-strand, but of course that is just my opinion.

This braid really is easy after you have practiced a couple of times. We'll be posting another fun hairstyle using this four-strand braid soon, so keep an eye out for that.
