They might be cute as headbands...I never thought of that. But I don't know if they would be more for decoration...I don't think they would hold hair place.
Can you share where you got these, I bought one like this (sold as a necklace/headband) and I LOVE it but the place that sold it doesn't have anymore and didn't remember what local person they bought them from. I really want more but can't even find them online, until now! Thanks, very cute!
