An inner frame - often fabric-covered - placed inside the outer frame to visually separate the artwork, commonly used in traditional or oil painting presentations.
A Frame Liner is an inner frame, typically fabric-covered (such as linen or silk), that sits between the artwork and the outer moulding. It creates visual separation and enhances depth within the overall presentation. Frame liners are often used in traditional, classical, and oil painting framing, providing a softer, more refined look than matting or simple spacers. They can also serve as a subtle decorative element that complements both the artwork and the outer frame.
