For the place settings, I made edible nests (for the DIY, click here) and little penant flags for the names.
The owl pops were made from an owl mold that I purchased at http://www.bakeitpretty.com/.
For the guest book, we thought it'd be fun to get a theme-related children's book and have guests sign inside of the cover. What a great, useful keepsake!
For the official favors (guests wrapped up the owl pops and their edible nests as well), I made sugar cookies with chocolate ganache icing in the shapes of a squirrel and an acorn (yes, the cutters were from Bake It Pretty as well!). I loved the forest friend scrapbook paper I found so I simply printed the message on it and matted it against the green to give more color. The twine bow helped keep a more nature-like feel.
The banner hung from the mantle.
Here's a few shots of the delicious brunch foods and their presentation.
