A yarmulke, also known as a kippah, 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. Yarmulkes can be made from various materials, including cloth, leather, or knit, and come in different colors and designs. Wearing a yarmulke is common during religious practices, such as prayer and attending synagogue services. Some individuals choose to wear it at all times as a sign of their commitment to Judaism. The practice of wearing a yarmulke is rooted in Jewish law and tradition.
