Covering hair while styling?

[aforestfae]

I love heatless curls but don't do them because I don't like walking around with sponge rollers/straws/mini bun things on my head, plus having my hair uncovered can make a terrible tangled mess the next morning when doing heatless curls.
What are some ways to cover your hair while you sleep and curl your hair?
I did wonder about a scarf wrap but I'm not sure how to do that as I've never done it before.
I did used to use a square scarf while pin curling but it doesn't work so well with straws
Any ideas?

You could try a silk sleeping cap, they seem to be popular around here. :)

Silk or satin bonnets would be your best choice. They now have more designs that fit all types of hair lengths. For straws a bandana/ triangle size would be best, or one with a drawstring and large cap would also work.
