This customer (who happened to take one of my workshops and heard how helpful it is to know a bit more about the occasion/purpose for an arrangement to help the designer in evoking the right emotions) is looking for 2 vases (pronounced vozez) of holiday greens for her Christmas party buffet table tomorrow night. She wants them to be JOYFUL. Question: What can I add to make the Greens Joyful? Painted birch, ribbon, glittered ting? Any, all suggestions would be helpful. Thanks.
