How to make very fine, straight hair super curly?
My 4-year-old daughter wants to be Merida from Pixar's Brave for Halloween this year. She already has the bright red hair, but it is very fine and completely straight. How do I get the tight curls Merida has? And how do I get it to survive the antics of an active 4-year-old long enough to go Trick-or-Treating?
