5 year olds.
The little videos are of the children creating their own colours from primary colours and black & white paint.
They were painting the entire surface of the paper. When it dried, they drew their monster on the back and cut it out. They turned them over, added details with markers and added white eyes.
Prior to making these monsters, the children drew their own monster with black marker. They also drew a little one while the paper was lying on carbon paper. This was fun, especially seeing their faces when they realised what was happening. They coloured the side they liked best, with pencil.
