For our tree themed wedding we wanted our guests to receive something to allow them to plant a tree and think of us as well as give back to the environment. We purchased these beautiful cards that open like matchbooks with douglas fir tree seeds inside: http://www.treebeginnings.com/evergreen-tree-seed-favor.html We used these as escort cards and favors all in one. I wrote the name of the guest and the table number (which were actually tree names) and we used plastic florist forks to put these all lined up in beautifully stained planters with herbs planted inside. A GREAT decoration for the cocktail hour as well as a great way for guests to find their seats and bring home their favors. This company was so helpful via phone and email. They made our day special!
