Garlands are an easy way to add a dash of seasonal cheer for Christmas, Hanukkah and New Year's. What's cool about the variety and price range (from around $20 to $500) is that you can mix up styles that blend with your existing decor. Metallic shines in both traditional and modern rooms, adding warmth and sparkle, especially with candlelight. Suzanne Kasler's mercury glass ball garland does that with lustrous tarnished silver (from Ballard Designs).
