First of all, pick a fabric that matches your hood and cut 4 3" triangles.

Now cut 2 slightly smaller triangles out of a contrasting fabric.

Use your sewing machine, or needle and thread to sew the small triangle on to one of the bigger triangles.

Place the second big triangle on top of the this one, with the smaller triangle facing the inside. Pin this in place.

Sew the two bigger triangles together, leaving a small gap at the bottom.

Fold inside out and stuff with a small amount of stuffing to give the ear shape.

Fold the rough edges under and sew along the bottom of the ear.

Make two of these.

Pin your ears in the position they look best on the hood. Take a needle and thread, go sit in front of the TV and stitch the ears in place. Meow!
