For starry eyes, twinkling teeth or extra oomph, a sparkle or two can come in handy.

  • In a new image, select the line tool and white paint.
  • Create a diagonal line at 45 degrees by holding down shift while dragging the line tool to a desired length.
  • Select Filter-> Blur-> Motion Blur at 45 degrees, desired distance.
  • Create another diagonal line in the opposite direction (-45 degrees) to make an "X" and repeat the last step with the Motion Blur at -45 degrees.
  • Lastly, select a paintbrush with faded edges and desired opacity and just smack some white paint in the middle of the X.
Rotating, resizing, or copying the sparkle takes care of the rest.

This is for those who like to create their own.
