When we want to create mass in an arrangement, it is often easier to use floral materials like spray mums, baby's breath or alstroemeria. These flowers are easy to bunch together, leaving very little space visible between them.
For this arrangement, however, I challenged myself to create mass with lilies. The reason is simple: I had a lot of lilies leftover!
I used two black containers to highlight the yellow of the lilies. The mass was set on top, accented with solidaster and one chrysanthemum bloom below to regain some balance.
Here is the whole arrangement.
I hope you like it. --Miyako
