This traditional origami rabbit is cute and easy to make. You can probably make it in less than 5 minutes. Sometimes, simple is best. The model can be made flat, or it can be made to stand upright.
Traditional Origami Rabbit Instructions
If you are using origami paper, start with the white-side facing up. Fold the paper in half (left to right). Unfold.
Fold the left-edge and right-edge of the paper towards the central crease.
Fold the top-edge of the model to the center. Unfold. The crease will be a 1/4 of the way down from the top.
Make valley folds as shown so the top part of the model splays open.
Fold down the back-layer of paper and press the corners flat (red dot).
Turn the model over.
Make the ears of the rabbit more narrow by folding the top of the model as shown.
At the bottom of the model, fold in the corners.
Fold the model in half (left to right), then rotate quarter turn counter-clockwise.
