Begin a biography of yourself with the day you were born. Include your parents and siblings and other immediate relatives. Give geographical information as well. Then begin documenting events of your life, graduation, careers, marriage, children, etc. Include all you feel is important that someone know about you.
Make a biography is bascily just writing down information about yourself. Just make a draft of what you are wantting to write about yourself and than write the biography. For more information look here: http://www.lovetosew.com/ragquilt.htm
