Use a freshly iron and starched square napkin. Fold the napkin into thirds, bringing the top third down and the bottom third up. Form a long rectangle. Press the napkin.
Fold the napkin in half just to crease to create a center line for reference. Fold the top corners down along this line. Press.
Fold up from the bottom along the dotted lines. Press.
Bring the left and right edges together on the center line. Press.
Flip over from bottom to top. Turn up the bottom point. Press.
This last part is a little tricky. To fasten: fold the left and right corners back. Tuck the corner of the left side into the fold "pocket" of the right. Turn the ears until you are satisfied with the look. Open the base so the bunny will stand up.
