First, cut out the pieces.
Then Stitch the eyes. If making a black cat, there is no need to stitch the black of the eyes, just fill them in when the rest of the black is stitched.
Stitch the rest of the face and overcast the mouth. If using a color other than black, fill in the front of the ears with light pink or light tan.
Stitch the back. Stitch the ears in the same color used for the rest of the back.
Stitch the base and overcast the mouth edge.
Stitch the three pieces together and you have a cat!
