The Sock Curl...

 My hair that night-

take an old sock and cut the end off

Then roll it up like this... 

 

put your hair in a pony tail high on your head 

 

spray your hair to get it little damp 

then

 from the top of your hair roll 

your hair on to the sock... like so-

and then head to bed- and wake up and pull it out and you have a fun little wave!
It took my two tries to get it to work..
