Gyotaku is the art of taking prints directly from fish.
Before this became a form of art, it was first done as a way to keep record.
As part of the training of Samurai warriors in Sakai Province, the men were required to record the fish they caught by inking them and pressing paper to the inked fish.
First, paint a fish with acrylic paint.
Next, pick up the fish and place it on paper or material!
Press down on the fish to make sure ever area touches the paper or material.
Remove the fish and let the paint dry.
