Vintage seed packets either found at antique shops, the internet, or gift shoppes. These can help influence the theme of the reception. Use printed with beautiful renderings of fruits and vegetables in place of your table numbers. The packets inspire the emphasis on autumn colors, locally grown produce, and farm fresh dishes.
For your escort card area, try a wooden crate filled with soil. Use the vintage packets to identify each table and then stake the individual names in front of the packet, as if it were the actual vegetable. For an added touch use vegetable shaped card stock escort cards which correspond to the vegetable on the packet. This may be more difficult for large weddings, as numbers are easier to identify – but this also settles seating problems that may ‘sprout up’.
