A kippah, also known as a yarmulke, is a small, rounded cap traditionally worn by Jewish men and boys. It serves as a reminder of their faith and the presence of God above them. Kippahs can be made from various materials, including cloth, suede, or knitted yarn, and come in many colors and designs. Wearing a kippah is a common practice during religious services, prayers, and significant life events, such as bar mitzvahs and weddings. While it is primarily associated with Judaism, some people wear kippahs as a sign of respect in interfaith settings or to honor Jewish culture.
