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.
Seasonal Decorations _ For those of you that desire to have your house decorated for each season, here a couple tips. Rather than decorate everywhere with everything possible, choose a few areas to keep festive for the seasons. This cuts down on storage needs and overall work. This could be a calendar area that is designed differently each month, or a shelf on the wall with craft items. Changing the clothing of a stuffed animal to reflect the seasons is a nice, safe way to decorate if you have little ones at home. One way to save money and space is to reuse what you have. Sometimes what may be considered as a very season_specific decoration can be adjusted to fit other seasons as well. Retooling your wreath is one way to save on space: instead of having a wreath for every occasion, use one wreath base and change out its decorations.
