Liner

Liner

Definition: A liner is a wooden moulding wrapped in linen fabric, designed to sit inside the main picture frame. It functions as a border or matting substitute for stretched canvas paintings, adding visual separation between the artwork and the frame while maintaining the structural integrity of the framing system. Unlike paper mats, which are not suitable for canvases, liners provide both decorative and functional support.

Characteristics

• Material: Constructed from wood and covered with linen fabric, often in neutral shades such as cream, beige, or off-white.
• Profile: Thinner and simpler than the outer frame, designed to complement rather than dominate the artwork.
• Finish: Usually left unadorned with plain fabric, though some may include gold or silver fillets for decorative effect.
• Placement: Fits between the stretched canvas and the outer frame, creating a step-down effect similar to matting.

Uses

• Canvas Paintings: Most commonly used with oil or acrylic paintings on canvas where paper mats cannot be applied.
• Decorative Separation: Provides a visual break between a busy or ornate frame and the artwork.
• Structural Support: Helps secure the stretched canvas within the frame without compressing the artwork surface.
• Design Element: Creates a layered or double-frame appearance without needing a second full frame.

Advantages

• Archival Safety: Provides spacing between artwork and glazing (when used), reducing the risk of sticking or damage.
• Versatility: Works with both traditional and contemporary frames.
• Aesthetic Appeal: Linen fabric complements oil and acrylic paintings, often softening the transition between art and frame.
• Customizability: Can include decorative fillets for added elegance.

Best Practices

• Select neutral-toned linen for versatility unless the artwork calls for contrast or accent colors.
• Match the liner's profile and color with the overall design of the outer frame.
• For conservation purposes, ensure the linen and adhesives used are acid-free.
• Consider a liner when a mat is not practical (e.g., for stretched canvases).
