Egg decorating is the art or craft of decorating eggs. It is quite a popular art/craft form because of the attractive, smooth, oval shape of the egg. Any bird egg can be facilitated in this process, but most often the larger and stronger the eggshell is, the more favoured it will be by decorators.
Many modern egg artists decorate their "art eggs" by etching or carving, while others paint or cover their eggs with different materials, from paper and fabric to polymer clay. Using eggs as a canvas has become so popular that special terms have developed with the art form. An "eggery" is typically a place where you can purchase supplies for egg art and the process of using a natural egg shell to create an art piece if often called "egging".
Egg artists also have their own guild, The International Egg Art Guild which promotes the craft of egg artistry.In the USA there are shows in many states where artists show their eggs and vendors of "egging" supplies can be found. Each year, the White House chooses a decorated egg from each State to display at Easter time.
