A simple symbol like a daisy is easy replicate in decor and favors. Not every detail is flower-shaped; yellow-and-white favors -- lollipops, rubber ducks, and paper cones holding penny candy -- are just as fitting; a gingham tablecloth is summery.
Treats can match the party's daisy theme. Display white-chocolate daisies sprouting from chocolate flowerpots on polka-dot paper. More chocolate blossoms in grassy planters invite guests to take their pick; floral tape conceals wood "stems."
A candy buffet is sure to please guests. Once you decide on a theme, you'll see ideas everywhere -- at grocery stores, drugstores, and candy shops, and in catalogs. Place candies such as lemon drops on cake stands, and jelly beans in a range of yellow hues are placed on cake stands and in jars. Although brownies aren't in the color palette, hand-drawn tags provide them with a party pass. We drew a daisy, made color photocopies, and taped them to toothpicks (cut points off).
A jar of lemonade has a handwritten label. You can add dots with a rubber stamp.
You can customize bubble containers for the party favors; their paper bands are affixed with double-sided tape.
