Outdoor Decorations

• Outdoor Valentine's Day decorations include hearts hung on small trees. Make these from red cardboard or purchase heart-shaped tree ornaments. Create an arch over your doorway with Valentine's themed cutouts such as hearts and lovebirds.
  
  

Indoor Decorations

• Place bouquets red, white or pink flowers -- roses and carnations work best -- around your house. Bunches of balloons hanging in the corners also creates a festive atmosphere. Candles also help bring in the Valentine's mood. Place Valentine's window decals in your windows.
  
  

Table Decorations

• Use a white tablecloth and sprinkle red glitter down the center. Scatter candy hearts and chocolate kisses around a centerpiece made of roses. Valentine's themed plates and napkins add to the effect. Tie a red, pink or white balloon to the back of each chair, or use a bow made of streamers or tulle.
