STEP THREE: Layer the panel on top of your white rectangle. BOTH LAYERS should be right side DOWN -- with the marked line showing on top. Sew directly on the line. I used my free-motion foot for this, for speed's sake and to avoid having to lift the presser foot and turn the fabric.
STEP FOUR: "Draw" on the eyes -- still working from the wrong side! Working from the back will make it easy for you to see your previous stitching lines and place the features accordingly. Again, I used my free-motion foot, but you could do this with a regular foot.
STEP FIVE: Trim away the excess white fleece to reveal your bird's eyes and white belly.
STEP SIX: Layer your black rectangle over the top of your bird's eyes. Be sure there is sufficient area to create his pupils and eyebrows.
STEP SEVEN: Flip it over and "draw" sew his pupils and eyebrows! He's looking ticked off now!
STEP EIGHT: Trim the lower half of your white fleece to match the red, then trim away the excess red, as shown.
The red angry birds do have a little black tail, which I chose to omit. If yours must have a tail, you can certainly sew a little tail using the same method as the head feathers, and attach it the same way as the beak. I suppose I may go back and add tails to mine!
