In woodworking, a cookie refers to a small wooden disc or puck that is commonly used as a portable support surface. Typically made from dense hardwood such as maple or birch, woodworking cookies serve multiple purposes in various applications. Their main function is to provide added stability and balance when working with irregularly shaped or uneven workpieces by creating a stable base for clamping or supporting. Cookies can also be utilized as makeshift feet for furniture assembly jobs where leveling and alignment are crucial components.
