Remember to keep in mind the vibe you're trying to achieve in your overall wedding design. Tall floral centerpieces are great, but maybe not what you'd choose for a more relaxed setting or a long rectangular table. It would prove difficult to see or chat with the guests directly across from you. Are you having a family-style dinner where servers will place various dishes around the table? If so, maybe opt for a cleaner tablescape so the food has a place to sit comfortably without feeling crammed amongst the décor. Buffet-style and plated dinners are easier to incorporate more decorations, but be mindful that your guests and/or servers must be able to easily navigate a place to set the table's dishes.
Below are a few of my favorite examples ranging from sweet and rustic; to clean and contemporary; to bold and colorful. Observe how fun it can be and how many options you really have! The possibilities, as always, are endless. Bon appétit, my friends!
