table centerpieces: tables for 8
1 candle pillar or 3 floating candles
2 photos – either childhood or old wedding photos
1 fish/plant or flower arrangement (Costco flowers)
favors???

I'm thinking a litle tin or organza bag of personalized M&M's (they totally will change the M logo for you!) or seeds/pots or decks of cards or wine bottle stoppers or some such thing.
