My Fiance' and I decided we want to have a tree themed wedding - it celebrates life and longevity!

And we are from a very rural area (our families are not) - we love the trees in our area - especially all the colors around this time (and next year for our wedding).We found a few things that we love - a wedding guest tree, a cake stand, tree centerpieces, and little tree favors. So I have a few questions.1. Is it too much? Especially if we were to put trees on the invites/save the dates. 2. I found tree centerpieces, but I'm not sure if its exactly what I want....Does anyone have any other ideas?3. Any other tree aspects to include? Thanks!!!
