After closer inspection I suspect they are fine bird feathers? Kind of grosses me out to get too close but after I was joking about practical uses for Chloe's natural hair loss I now see that this may not be one of them. It all started when we were setting up the deck chairs and I was pulling cushions of the plastic storage box. And my first assumption was that the squirrels had nested in there but who knows? I was initially trying to brush it off but then realized it was actually embedded into the cushion...and it's not the original stuffing inside!
