First, fill a clean vase with water. Second, cut most of the flowers and greens sothey are approximately two times the height of your vase. Then, cut a couple of the flowers two inches longer. After you are finished cutting the flowers, you can begin to put the greens in the vase. Now add the other flowers. Start at the outer edge of your vase. Put the longest flowers in the center of your arrangement. Then take a few steps back and admire your bouquet.
