To make these cute easter bunny napkins first you have to fold a square napkin in half making a rectangle. Fold the napkin again. Join both the sides to meet in the centre and you will get a shape like in step 4. Fold the downward parts to become a diamond shape as shown in step 5. Again fold both the sides. Fold the top triangle backward. Put one side into the other side. Put the napkin on a table and you will see a bunny formed.
