So let me show some examples.
Light and darkness/shadows:
Lamp by Kade Chan

Black and white:
Swans by David Derudas (Sry have not find a good black/white fold of these)

Lucky and sad:

So there are many other possible contrast. For example you can design two puzzle pieces that fits together. So let ou your creativity and show us your contrasts

Rules:
- Any number of sheets or shape of sheets.

Good luck to everyone!
