Abstract
A method of recycling greeting cards. A first step involves making a greeting card body that dissolves when exposed to water leaving negligible residue. A second step involves incorporating in the greeting card body a substance that is released when the greeting card body dissolves is water. It is a desire to release the substance that provides a positive incentive for placing the greeting card body in the water.
