Keep it simple! My son was married 1.5 years ago and the whole thing was less than $4000. Flowers from my garden and my father's were used for bouquets for rehersal dinner tables, wedding and reception tables. Rehersal dinner was at our house--subs and salads--the wedding was at the historical church down the road--and the reception at a log cabin pavillion with sides and fireplaces for free to those who live in the town. The bride planned all the food--and helped make some. She planned the decorations for the reception and showed us what to do. Keep it simple!!!
My daughter says hers will be even less complicated. ;-)
