Question About Cosplay? I Need Help?

I want to go as Rin Kokonoe from Kodomo No Jikan(A Child's Time). It will be the first time that I've ever tried to sow a costume but her outfit is simple enough that I think I could pull it off. I even found a great wig. The problem is that she wears these large hair ornaments and I'm not sure how I would make those or find something that looks like them.

Here's a picture

you see those hair things? She wears eight of them. four on the top and four near the edge of her hair. Any ideas as to how I could make them or what I could buy to get that look?
