These geometrical paper cropcircle patterns are artistic renderings from photographs of actual Crop Circles which have appeared in various locations around the world over the past 20 or so years - most likely the work of humans, not space aliens.
The earliest cropcircle appeared about 2,000 years ago according to Bob Kingsley, founder of The Circular, the official magazine of the Crop Circle Connector (CCCS). Other mentions include historic sightings in the 1600's but most cropcircle sightings seem to have taken place since the 1940's to the present.
Use these images as guides for creating child-sized crop circle in more desirable places than farmers fields, such as playgrounds, drive ways, asphalt surfaces and sandy beaches.
Refer to the directions for making child-sized cropcircles for ideas and materials needed.
