thank you pop-up card

Simple cover that can be drawn as easily as if it were calligraphic writing.

This card is fast and carelessly constructed. 

The arm arcs upwardward 45°as if to gesture, "Here's some flowers."

The man is glued to the edge of the stepped platform, but anything can be glued there. His arm with the flowers is glued to half of the inside of the crimp. But it can be any content at all. 

Hints:

Do not become married to the content until you see how it works. Make sure the content tucks into  the card before gluing anything. Paperclips are useful for this. 

The crimp is a made directly onto a fold and cut across it and pushed inward so that it folds oppositely to the step. When the card is fully opened the step is completely flat with the card. It is only a proper step when the card is opened to the 45° position. That is how you can check for accuracy during construction. The card can be constructed and glued in its flattened state.

When the card is completely closed, the step folds opposite to the card and the crimp folds opposite to its step. 

Content (the arm) is glued to only half of the crimp. The crimp works in wonderful and mysterious and confounding unpredictable ways. Experimentation is necessary in determining which direction to cut the crimp and which half of the crimp the content will be glued. So two decisions there. In this case to lift a human arm, but it can be anything, a rising sun, a concealing bush, an animal head, anything.

The glue tabs can be any size at all. They can be concealed behind additional content, or they can be inserted through slots cut into the card. But this card is simple so the tabs clearly show. The glue tabs can be much smaller than this. They can be tiny extensions. 

You can see how the whole thing can be loaded up with more content. So much content that the tabs and the step platform are all concealed. I could surround the man in a swamp. In fact, the opposite side of the crimp can be used to attach an arm that lifts up a bush larger than the man. And the opposite side of the step can can be used for multiple crimps to be placed on the same step. There can be additional steps. There can be crimps that are cut in the opposite direction. To this day, I still cannot visualize in advance how the crimps will function exactly. I must experiment each time. Maybe you can visualize it better than I. 

I used two of these crimps cut into the same step on opposite ends in opposite directions, with content that overlapped, basically two discs, to make it appear like a dung beetle pushing a ball of dung. It is also how I made two overlapping discs appear like a snake uncoiling.
