If you really soaked the hair and FOAM rollers, it could take more than an overnight to dry. Take out just one for a test.

My favorite rollers to leave in for a long time (as in when someone gets boxed) are the Hairdo Hardware kit ones that are foam with wire inside. They twist around easily and are perfect for AGT length hair.

However, the original instructions for giving Molly "All American Curls" were to use the perm rods with curling papers and a spritz bottle. This is still the most effective way I find to add curls. I use very small sections of hair and lots of rollers. Brush out the hair, spritz liberally with water, pull it out straight, fold the curling paper in half across the end. Tuck the paper end neatly under the bottom of the roller and roll the hair all the way up to the scalp. When the doll's hair is all curled up, leave it alone for 24 hours. To preserve the curl, don't brush it out when you take it down. Just run your fingers through it.

I always set my dolls' hair before they retire into boxes, too. I use foam rollers for that, varying the sizes based on how long the doll's hair is. I use the large size pink foam rollers for the top of Felicity's hair, for example.

Don't use hot rollers -- it'll fry or melt your doll's hair.
