craft ideas?

I was cleaning the basement and found a huge box of late 80s/early 90s hair scrunchies. We're talking fifty or more. Although I was in middle and high school at that time, and was the prime age to wear dozens, probably at once (and did) these are NOT mine. They were probably sneakily dropped off by my mother-in-law, who saves everything.

Any craft or repurposing or game ideas? I have two pre-schoolers. At the very least I'll chop them up and put the fabric scraps in their craft/collage box, but let me know if you have any ideas to reuse them as is. Thanks!
