Faithful to the Ikebana principles of minimalism, I compose my floral designs with few flowers. The reasoning behind minimalism is based on the fact that leaves and stems are better suited to express the three points (man, heaven and earth) that govern an Ikebana composition. Depending on the place where the arrangement will be used and the season, I may use a single gorgeous flower, which can be very effective in creating a pleasant aesthetic impression. But the focus of my arrangements is to recreate nature. So, as a rule of thumb, I tend to keep my compositions rather simple. As in Ikebana, simplicity and minimalism are at the heart of my designs.
You have all the time to rearrange or polish your flower arrangement. The flower design should look beautiful and artistic enough before you place your filler, when the filler is already placed, it would be harder to move your things around the area or place. Bear in mind that The filler are very fragile.
