Consider repurposing certain facets of your wedding day as favors. A grouping of bud vases with tiny flowers makes for an interesting centerpiece, and guests can take one home at the end of the night. Or serve slices of wedding cake in pretty cardboard boxes with a message of thanks attached to each. Heck, consider copy one bride's idea of reusing her and her bridesmaid's bouquets as centerpiece displays!
