There are several types of line in an arrangement. Lines can express different moods and feelings just by the direction they are placed. Line provides a pathway for the eye to follow throughout the arrangement. The three main types of line are actual line, implied line, and psychic line.
I have noticed that western style gardens _ such as those seen in big castles, for example _ characterize themselves by man_made forms that generally follow symmetric patterns. In contrast, Japanese gardens, while also man_made, always try to recreate lifelike landscapes, by using not only botanical elements but also water, gravel, rocks and other natural components. In a similar manner, when compared to western floral arrangements, Ikebana compositions also have a stronger emphasis in reproducing natural settings.
