Actual lines are very obvious. The eye can easily follow the design to its height and width. Actual lines sets up the skeleton of the design. Actual line flowers can be curving and flowing within the design. Implied lines in floral design provide a pathway for the eye to follow but no actual line flowers are there. Although carnations are not line flowers per say, if they are cut one taller than the other that can create a line effect. Greenery can also create a line effect. As our eyes connect the upward graduating carnations we see a line result. The third kind of line is the psychic line. This is a line that does not exist, yet we feel the line outcome. Psychic designs are made by placing flowers in a manner that directs the eye up and throughout. Two tall birds of paradise can be placed high in an arrangement, while all other flora materials are rather short and to the base. The two tall birds of paradise create a visual line and bring the visual path upward. Many oriental designs use this technique.
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.
