Teddy Bear:
Glad you like it. And I'd be happy to. I don't have much experience, my Belphegor wig required virtually no styling, but my Tamao wig did, and I got a lot of compliments on it.^^
It'll just need some razoring and a ponytail though, so I could definitely handle it.
For the rings, I also remembered this foam fabric stuff that my little brother used for his Pikachu Halloween costume. Beautiful stuff, it would work perfectly. I'll try to remember to look up the actual name of it to tell you, I'll have to find it.
