In one sentence, describe what the following article is about:

Start by rolling two small balls of clay about the size of a pin head. Press each ball onto the sides of the angel's head, turning them into slight disks. Make them level with the dent, and position them closer to the face than to the back of the head. Use a clay tool, or another blunt-tipped tool, to blend in the front part of the ears towards the angel's face. Do not blend in the back of the ears. Choose some clay for your angel's hair. It can be yellow, brown, black, or even a surprising color, like pink or purple. Roll out your desired clay into a thin sheet. You can use an acrylic tube to do this, or simply press the clay between your fingers to make a "pancake." Use a toothpick to draw streaks into the clay going widthwise. Be sure to cover the top of the head as well. Don't cover the face. Smooth the top of the sheet over the top of the head. If you'd like to, you can add a parting crease with a toothpick. Roll out thin coils of clay, then attach them to the front of the hairline. They can be as long and wispy as you'd like. For a more realistic effect, have all the smaller hair pieces come from the start of the part. Consider adding some streaks to the bangs before you attach them to the head. To make curls: attach tip of coil to head, twist the other end into a coil, then position it using clay tools or a toothpick. To make blunt-cut or straight-across bangs: roll out a thin sheet of clay, then cut it down to a triangle or rectangle shape that will fill in the gap on the forehead. Press it onto the forehead.
Add small balls of skin-toned clay for the ears. Blend the front part of the ears in only. Roll some hair-colored clay into a sheet and add streaks into it. Wrap the sheet around the angel's head to make the hair. Add smaller pieces for the bangs.
