The brilliant blue feathers of the male and the softer blue of the female Bluebird bring immediate delight to bird lovers. Did you know, though, that the feathers aren't actually blue? The color is created by "prisms" within each feather and how the light plays off of them.  So fascinating...just like many other aspects of these beautiful songbirds.
 
This 8-card collection feature gorgeous photos of Bluebirds. There are two cards of each of four images: in flight, at birdhouses, and in nature's house within a tree. These are sure to bring delight to you and the recipient of your thoughtful note.
 
Details:
The 8 beautiful cards come with linen envelopes.
The cards and envelopes are packaged together in your choice of either a sheer vellum envelope, or a lovely organza bag. Either will keep your cards together and also package them as a beautiful gift. 
The folded size of the cards are 4.5x5.5" -- smaller than the Wren greeting/note cards that are sold individually.
Printed on a matte paper that has a nice weight for writing and speaks of quality.
