Bird themed centerpieces

My brother in law proposed! Jacob and Jill will be getting married some time this summer.
Their theme....."Love birds".
I LOVE it.
We went over some centerpiece ideas. Here were my favorite in order from least to greatest.

Bird nests with flowers instead of eggs

How easy. Branch (back yard) + spray paint + birds = beautiful

This is the feel we are shooting for. Caged flowers. Cute, eh?
