Oh, ask SimplyPrincess about Twillies and her DH ... sorry, couldn't resist. Mental picture hasn't left me in a couple days!!
As for my twillies, I tie my hair back like a headband or around a ponytail. I also have used them to wrap around the handles of my birkin or my kelly. They also make an adorable bow to decorate said handbags. And they look really cute around my neck!
