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.
Traditional flower designs do not make use of any accessories apart from the vase, but rather the focus is on the number and colours of the flowers. Oriental flower designs focus on the appearance of the arrangement, linear lines that emphasise the negative spaces and texture and form of the flowers. A modern flower arrangement includes the minimal use of bright flowers and more accessories. It does not follow the traditional outline of arranging flowers as the styling depends solely on the preferences of the designer.
