Red and green are excellent Christmas colors. The problem is to keep the presentation from becoming a carnival of color. You can achieve this by grouping the reds and greens separately. In this way, you will create a soft image. Good presentations result from mixing plain and extravagant materials to achieve a balance. Place the shiny Christmas balls in bowl of real willow branches.   Then place a plain glass vase in a slightly extravagant display window with willow branches.
