Fall Wedding

I`m getting married Oct 15, 2006 and need help with centerpiece and flower ideas. My bridesmaids dress colors are 2 girls peridot, 2 girls wine and the MOH chocolate brown I was thinking of having each 2 carry one type of flower the MOH carry another and then my bouquet would have all three flowers. I`m using votives with pumpkin spice candles and sprinkling silk fall leaves around the cake. The head table so far has fall leaf garland silk fall leaves and votives. I was also thinking of getting vases and having the girls place their bouquets on the table in front of them but I would like to dress up at least the parents tables and need ideas for those as well as cheap centerpeice ideas for the other tables. The head table is rectangle and the rest are circle. Any pics would be helpful. Thanks
