Hello folks!
Here's a simple and fun card that I made for a sweet little kid. It folds up to look like a tiny thin book but when you open it, it has a nice 3D effect. First, you need 4 sheets of paper which are squares. I took about 7cm sized papers.
There is a nice video card tutorial on YouTube.
I folded them and cut them like below.
Fold them further. And stick them to each other.
Then I pasted some printed papers as shown below.
I added some trims to the front side and pasted two felted hearts.
And tadaa !
