Doll rollers can be made from any plastic cylindrical material you can find.
Some people use straws, others use vintage metal permanent rods.
My personal favorites are manufactured by Olivia Garden. Doll bobby pins however, are a thing of the past and those, like hair wave clips must be searched for at antique shows or on eBAy. This site has been Netscape enhanced. If you are using another browser, it will not look as it was intended.
