If your tablescape will preside over your dining room table, you'll want to incorporate your tableware into the design. Clear glass serves as a good neutral dish option for a colorful landscape. Display fall leaves under the plates or find large oak leaves to replace napkins for setting silverware.
On the other hand, you can opt for some tinted glasses and plates to provide the color in a sea of neutral decorative items. Holiday-themed dishes and serving platters are great for holiday meals, or find platters and plates shaped like leaves and pumpkins for a more general fall feel. For a rustic touch, set wooden or twig placemats.
