Take a holiday design cue from decorating editor Lindsey Ellis Beatty and trim a fabulously festive tree based on the colors of your own room, not Santa's coat.
Give traditional ornaments a monochromatic look by spray-painting them all white. It's an easy way to update old ornaments or create an instant collection that feels familiar and loved. And go up and down, not round and round, with your garlands. Drape them vertically to emphasize the tree's height, and finish off with swags at the bottom rather than letting the ends hang straight.
