Propagation: Are these Achillea seeds or fluff?, 0 by GardeningMommy

HELP!

I was supposed to send someone seeds from my Achillea millifolium 'Paprika.' I let the flowers dry on the plant, then tried to gather them over a white piece of paper, but I'm not sure what's seed and what's just fluff from the dried flower (I've never collected seeds before)! There are hundreds of similar looking little things that I think might be tiny little seeds, but I'm not sure, and I don't want to send dead flowers rather than seeds. If these aren't seeds, then apparently my plant didn't produce seed this year, because there's nothing else that even remotely resembles a seed. I'll post two pictures of them. If you have achillea seeds that you could compare these to, or if you're very familiar with seeds, please let me know what I've got!

Thanks.
