A kippah, also known as a yarmulke, is a small, rounded cap worn by many Jewish men and boys. It serves as a reminder of their faith and the presence of God above them. The kippah is typically made from various materials, including cloth, suede, or knitted yarn, and comes in different colors and designs. Wearing a kippah is a common practice during religious services, prayers, and significant life events, such as weddings and bar mitzvahs. While it is primarily associated with Judaism, some people wear it as a cultural symbol or for personal reasons, regardless of their religious beliefs.
