Round floral arrangements
In this case, we use spikes or hard foam. With five flowers of equal length, we outline the circumference and the height of the arrangement. The remainder of the flowers, which should all have equal stem lengths, should be inserted in between. Fill out with leaves.
Triangular floral arrangements
Mark the outline with three flowers, two of equal length and the one to be inserted in the middle of the arrangement, a little longer. The remainder of the flowers can now be divided within this triangle. Here, also some leaves or berries can be used to add accents.
Irregular triangular floral arrangements
The first stem should be twice or three times as high as the vase. The second stem should measure two-thirds of the first, and the third stem should be one-third of that height or even lower.
