craftgrrl | Little birds

This summer I'm going to be moving into a new place, so I'm slooooowly collecting things in which to decorate. Means I can get things on the cheap and really plan, you know? I picked up these little bird beads the other day; there are five of them and they're only about an inch big. Teeny! But they also match this really sweet bird dish that I keep by my bed. I want to hang them in my windows.

Now, I'm planning on painting them, sticking a hook inside of them so I can hang them, and filling the bottom hole. I'd like to give them the same glazed/glossy look that they have here, after. They've obviously been fired, and the seller told me they were porcelain, but, he could be wrong.

SO.

a) what would I use to paint them?
b) what could I use to fill in the bottom hole?

(if the picture is screwing up anyones f-list, let me know, and I'll put it behind a cut, but I tried to keep it tiny)
