Cute napkins. As I mentioned HERE, I love the Ikea ones. They are cheap and instantly make your food table look purposeful. Go with plain plates (because they are cheapest and sturdiest at Costco) and go for the sassy napkins.
Tangy Garlic Aioli: Cheese, crackers, and fresh veggies are a bridal shower staple, but they can be a bit expected. Jazz them up by serving interesting dips and spreads alongside. This tangy garlic aioli kicks things up a notch, but you could also make a sweet/savory Pineapple Cheese Ball, a green goddess dressing, or a spicy remoulade.
