My daughter loves the scrunchies.
I have very long, thick hair, so I go through a lot of hair ties and scrunchies. This is my favourite; it's durable, easy to wash, and looks great. I've had my scrunchie for about a year and it's still in the same shape (which is a huge feat as they usually stretch out within a few weeks). I have the clementine design, as well as a sunflower one that isn't made anymore, and will continue to stock-up on these amazing and carefully made items until she doesn't make them anymore.
My recommendation is to use cold water and Soak to wash them, and hang them out to dry.
She makes very cute and beautiful scrunchie.
