You could create an arrangement for any size vase, the larger the vase, the more flowers and greens to use. For Christmas time, use red, white and maybe even green flowers (like green button mums). Also choose from a variety of greens and evergreens out there. Accent a red rose in a bud vase with some baby's breath and cedar. Deep red alstroemeria are especially beautiful. There are many other flowers that would be perfect to use for Christmas arrangements, the link below will take you to a complete list of flowers, foliage, and evergreens for Christmas floral design.
The primary position in a florist is the lead flower designer. This job could be fulfilled by the owner, a manager, or another employee and the task is to create designs using flowers. Even though this may seem pretty basic and simple, it is a very critical position. Every completed floral design will be judged and represents the quality and creativity of the florist shop.
