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.
Picking your flowers (and vase) _ When selecting your flowers, try to pick a few colors and shapes that will work well together. You can go with a monochromatic design (all one color) for a contemporary look, choose all warm colors for a strong happy statement, or mix every color you love for a natural feeling that will bring the outdoors indoors.
