Even on a budget, you can achieve a beautiful and elegant atmosphere for Thanksgiving dinner. Cover the table with a brown cloth. Search for a tablecloth that is on sale, or if you have access to a sewing machine, purchase some cheap fabric and sew a tablecloth. Shimmery paper makes an affordable place mat. Don't purchase new china; instead, use what you have on hand. Plain cotton napkins are environmentally friendly and inexpensive.
For a set of wine glasses, cutlery, and tealight votive holders, look no further than Ikea. It's a great place for large quantities at a low price.
Add an element of nature to the table with homemade place card holders. Write the names on the same paper as the place mats. Cut out and attach to a pinecone or tree spur with a satin ribbon. Avoid going overboard on the flowers; one simple bouquet is enough. Purchase the flowers at your local supermarket (instead of at a floral shop) and arrange yourself. Safeway and Trader Joe's usually have luscious bouquets for under $10.
