If the flowers appear too bunched up, try cutting them at different lengths for more variety. Don't worry if some blooms don't stay in exactly the right position at first. Continue to the process by adding more flowers, adjusting their height and position as you go. The stems should all fit comfortably in the neck of the container and begin to hold their positions better as more flowers are added.
Japanese flower arrangement, also known as Ikebana, focus on the line of the twigs and leaves, rather than on the flowers themselves like in Western designs. The line of the twigs or leaves is combined with a small number of blooms and the design is complemented by the style of the container which is also a key element in the Ikebana style.
