Place your ornamental cut flowers into your water vase, make sure that you put it one by one. If it's going to be a design or floral arrangement against a wall or flat surface you have to put the tallest or longest cut flowers at the back. If your design or flower arrangement will be visible from the sides place your longest or tallest flowers in the middle. Begin with the longest or the tallest, and then go out to the lips or edge of your flower container. Now, take time to look at your flower vase, is it beautiful and pleasing to see? Did it turn out to be symmetrical? Is there a spot or an area that needed to be filled in with more flowers?
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.
