So, I was thinking about buying a gift card box or bird cage or something for people to put cards in, but none look close to the theme and it seems like a simple DIY project. I was looking at a couple of pics, and my silly question is this, why are there two or three boxes stacked? Is this just for the look, or is there somehow another usage of the other boxes... I was thinking that maybe they cut out the portion of the box below the others...?
