Wedding in Red – Perfect Marriage

I’m having an outdoor wedding on my Uncle’s ranch in Texas near San Marcos in late April to Early May. My colors will be bluebonnet blue and white with a hint of red. My wedding site has very large oak trees around it and a river on one side, however it is mostly hidden by trees. My reception is taking place in a civil war-era mansion that has a large hallway running all the way through the first floor of the house from front door to back door. Both the front and back doors are french doors that lead out onto covered patio/porches. The hallway ends at a large stone floored and walled living room which has the french doors in it and has it’s left hand wall covered in shelving. There is a fireplace on the other wall. I’m thinking about doing a sunset wedding… or a little sooner, to capture the beautiful Texas sunsets, therefore the reception will be at night and I’m probably going to use candles for a lot of the lighting. Any ideas on how to decorate this reception and wedding rustic but elegant? I’m looking for unique and tried and true ideas… I wish I had pictures but do your best with what I described .
