I have blue and white accents throughout the house, so these complement the decor very nicely.  For Christmas, they will be placed in glass vases with holiday potpourri, ornaments, pine cones, and greenery.  They are versatile enough to use throughout the year, either mixed with other accessories, or in a bowl or vase by themselves.

Pros: Blue color and patterns go well with blue and white ginger jars and other porcelain pieces.  The 3" size was just right.  
Cons: Some of the balls had tiny nicks.
