What makes a mantle, banister, tablescape garland look "real"?  Mixing a variety of greenery is what makes the difference.  Layering pine, cedar, and perhaps holly will make your decor look as though you gathered fresh boughs.  Then add some lights, some pinecones, perhaps some ornaments or candles, and you're done!  
 
This 6' cedar garland is exactly what you need to make it look "decorator perfect".  The cedar boughs can drape over the front of the mantle or console table, adding visual interest to your garland.
 
Buy several.  They will look beautiful season after season, and you'll be glad you did.
