How can I put hats over Lego Friend's hair?

[badbob001]

I want to put hats over girl hair, like the hair from Lego Friends. Since the hair piece has a hole on top, there must be a system way to use it to keep hats on. Any ideas before I resort to fun-tack? The closest thing I can think of is to use this to keep the hat from slipping off.

The hole on top is designed for accessories like the one you just posted a picture of, not hats specifically. There ARE a couple hats designed to fit those kinds of holes, though: this nurse hat from the medical accessories prepack and this hat from The Lone Ranger sets (also available in red from the LEGO Movie Minifigures series). The solution you suggested, using a small accessory like that star to keep a regular minifigure hat in place, might work as well!
