My Ears

So finally got my ears made! They look waaaay better then I expected, thanks everybody! (Can't usually sew two pieces of fabric together, so wow!)

They turned out heavier then expected and won't stay on my head now though. :(

I do have a black wig I was gonna use with them if that helps any.

My question is - how do I make 'em stay on my head now?
Edit: Actually, clings pretty good when layered over wig, but will be worn for 8+ hours at work, so any tips to keep it in place appreciated. Same with wig, though it clings pretty good.
