The June Challenge is HALF or HALFWAY or MIDDLE. Open to your own interpretation.
You can center your subjects or you can look for themes like Halfgrown, Halfway across the street, Halfway up a wall or Halfway across the sky.
Or perhaps half open, halfeaten, halfasleep, halfdone, halffull, halfdressed, halfbuilt, halfpint, perhaps halfhearted or even halfassed *:)
Half of a pair, like a partner. One shoe. One earring.
