Cornrows & Straw Curls

Can anyone give me step by step directions on how to do cornrows? How long does the hair have to be? Also, what are straw curls? How do I do them? Thanks

It's best that you watch someone do it slowly to learn but I'll explain it as well as I can.
1.Part the hair on both sides as far back as you want the braid to go creating a row of hair. You should practice using a section of hair that's neither too big nor to small.
2. Section a small part of hair at the hairline into three pieces.
3. Using either the left or right hand- whichever is more comfortable for you- place the first piece under your pointer finger and hold it there with your thumb. Place the middle piece on top leaving it free to work with and hold the last piece with between the thumb and the pointer next the first piece.
4. Take the free piece on top and hold it between the thumb and pointer of the other hand.
5.Push your pointer under the first of the two other pieces of hair while picking up a little piece of hair from the scalp at the same time and hold the last piece between your thumb and pointer.
Reapeat steps until you reach the end.
Your hair only has to be long enough so that you can hold it between your fingers comfortably.
It's kind of hard to braid your own hair at first so I recommend practicing on a doll or a friend.
