I had seen a tutorial for this on Heather Summer's blog http://www.stampwithheather.typepad.com/ a while back but she did another for SCS a few weeks ago. I decided to give it a try for a fellow blogger's b-day.
I really love chic-n-scratch's blog http://www.mychicnscratch.com/ and in honor of her bird theme pulled out some retired DSP and a current favorite SU set Aviary. The tutorial is pretty easy but there is something wrong with the measurements of the second level so I has to kind of "wing it" (no birds were harmed in the typing of this pun).
I like the color combo of pacific point and old olive. The ribbon I got off the SU clearance rack. The button is also Stampin Up. With more thought you could probably make one huge long bird cage on the card but I like the balance of having several.
