Designers of contemporary collections often combine flowers with fruits to make their arrangements good enough to eat, an abundance of fragrant sweet peas displayed in a vase full of strawberries give a terrific look to any summer dinner party. Slices of limes and lemons work wonderfully with white roses to give a clean crisp effect. Miniature trees, stripped of their leaves and replaced by single heads of pastel shades of asters provide an interesting focal point for a large room.
You may start by placing your foliage that you will use in a water vase. You have to make sure that you keep it around the lips or edges. Stick with the plan to place them the lips or edges of your water vase with a layer of your Foliage. When it is too big or too thick, it ends up detracting from your cut flowers. And if it is small or too thin, visual contrast will not show.
