My favorite decorations for Christmas are:
Lights, usually plain white, but also a variety of colors.
Overall decorating theme, fresh green and variations on white.
Reflective, silvery ornaments.
Indoor tree, white with blue ornaments.
Trimming for the house, fresh greens, juniper, fir and pine.
Angels and snowmen, polar bears, penguins, deer, reindeer, moose, gingerbread men, gingerbread houses, and peppermint candy canes.
Red plaid ribbon.
Outdoor tree, snowy fir or pine.
Linens, burgundy velvet, white lace.
