In order to capture the warm ambiance of a rustic-themed wedding, burlap is the iconic material that will complete the look. You could also incorporate other earth-toned material and details, such as pomanders made of burlap and dried leaves, flowers, and twigs. The neutral, earthy colors will evoke a feeling of warmth, and remind the wedding party of home.
It may not be a good idea to cover everything in burlap, however. A maximum of three major details that are in burlap will suffice. For example, if your aisle runners and table runners are in burlap, the last burlap detail you could add would be these personalized vineyard motif burlap chair covers:
You could also swap the pictured satin ribbons for hemp or twine. You may also try having burlap seat covers, a burlap aisle runner, and then add the last detail of burlap silverware holders to be subtle and not overdone with burlap overkill. Your ideal rustic wedding awaits!
