WOW, Nonie! That is GORGEOUS!!! How did you do the second style? Do you have a tutorial?
The second style, fondly known as my Lisa Simpson Hairdo was really a fluke.
My hair was not stretched (S Curl, my favorite moisturizer causes my hair to shrink down on itself), and because my hair was longer than when I did the first style, the shrinkage cause there to be a lot more hair when cornrowing so that I could only seem to form fat, chunky cornrows, instead of the sleek, slim ones you might see on folks with relaxed hair. Usually I will leave the tail ends of the cornrows un-plaited and just comb them to blend in with the rest of the hair in the back. But because of shrinkage, I just couldn't get the ends of the cornrows to blend.
I spent many minutes trying to fan out each cornrow end and comb it together with those on either side, but the hair would just separate into what looked like crazy palm trees. In the end, I threw in the towel and let my hair win. I patted it into place and hoped it didn't look too crazy. To my surprise when I went to the b/r and had a gander at the do later in the day, I was smitten. A coworker had just said she liked my little puffs, but I didn't know what she was talking about coz at last check before I left home, the palm trees look was not at all cute. It wasn't until that trip to the b/r that I realized she really was right that it didn't look half as bad as I thought. I forget who christened it Lisa Simpson (maybe it was she) but I have since called it that and it is now one of my favorite inventions.
So the secret to the style is to have 4B hair shrunken
like this and then cornrow and you will find the end of each cornrow will just be antisocial and keep to itself. I guess if you don't have hair that shrinks so tightly or if your hair is just not long enough yet, you can force the issue by using something that offers some hold and just use your fingers to pat/mold your hair to create the puffs.
If you find it easier to cornrow stretched hair, maybe spritzing your hair with some water-based moisturizer once you're done can cause the ends to behave like mine did.
