Summarize this article in one sentence.
Take your left ear and place it on the left side off a thin, metal headband. Position the ear how you want it, then pull the ear down until the gap covers the headband. Pin the gray and white fur together under the headband with a sewing pin.  Repeat this step for the other ear too. The gap allows you to pull the gray and white fur around the sides of the headband. If you are using hair clips, simply sew a hair clip to the bottom edge of each ear. You don't have to do this, but it can give your ears more depth and make them look more life-like. Choose a paint that's a few shades darker than your gray fur, then air brush it onto the edges of the ears. Extend the color down the tip of the ear and onto the back.  Add some light gray paint to the inside if each ear. Make it go down to the middle, just to the side of the longer fur. Let the paint dry, then comb the fur out with a pet brush or pet comb. This will help break up any chunks of paint.

Summary:
Position the ears over a thin, metal headband. Add details with an air brush, if desired.
