For this baby shower, a variety of roses and tulips were arranged in a collection of sterling baby cups and silver goblets by event designer and friend Sally Shay. Using the baby cups reinforces the theme. Petite arrangements make a big impact when grouped together; they also require fewer flowers than a larger arrangement. Selecting a container for your centerpiece will determine the amount of blooms that are needed. Don't limit yourself to goblets or vases. You could incorporate a variety of teapots and teacups.
