Cut the stems of the greenery so there is enough stem to layer and wrap with floral wire (about 2-3 inches of stem).
Starting with the fullest plant, arrange the greenery in a mock format and place it on the floor or table at the approximate length of the finished garland. Continue the mockup design by layering accent fill at the base of the garland.
Starting at one end, take a bunch of greenery and begin wrapping the floral wire around the stems, placing one bundle after another. When layering, be sure to cover the floral wire from the previous group. Continue layering greenery and wrapping floral wire around stems until desired length is reached.
Prepare the water tubes by filling them with water. Cut off excess stems and leaves from the main stem of the flower and insert it into the water tube.
Arrange the flowers throughout the garland and place them in place.
