Step 3 - I find the trick to arranging flowers in a round container is to think of the face of a clock...
I start with the greenery. The first step is to put the hour and minute hands in the center of the imaginary clock, which is really the center of the container.
Next, I arrange additional greenery at the quarter hours and then fill in all the hours of my imaginary clock with more greenery.
The last step is to add the flowers. This is simple. I follow the same procedure with the flowers as I did with the greenery.
Design Tip: Cut the lateral flowers off the main stem from both the spray roses and button mums. Use these smaller pieces throughout the centerpiece instead of using them as one whole stem.
Now flower arranging is as simple as clockwork.preservative.
