In our wedding, we didn't have a ring bearer, because a) we didn't know any boys little enough for the job, and b) I've seen too many cheesy ring bearer pillows. Turns out I didn't look hard enough. If I could have a re-do, I might have had the flower girl carry the rings down on one of these adorable "pillows" (more like ring displays). My sister served as our flower girl and carried down a small, moss-covered basket filled with petals. To fit the theme, I suppose she could have carried this instead:
A little bird's nest holding two rings would definitely have fit the bill. Here are other ring bearer "pillows" I found on Etsy--it seems you really can find a fitting display to get those rings down the aisle in style.
