I cut hydrangeas from my parents bushes (they have oddles of them!) and put them in vases with lemons. I love the happy combination of flowers and fruit! All the yellow napkins were from Home Goods and I did varying ones with white, yellow designs and solid yellows down the entire table.
I put a little tag (made out of the leftover invite cardstock) in each of the water glasses so each person would know where they were sitting.
