Cotton Drawing Backing KOH-I-NOOR 27×33 cm – 430471

KOH-I-NOOR cotton drawing backing 27×33 cm is a natural cotton support sheet sized for small-format art and craft projects. The 27 by 33 cm cotton backing is intended for mounting, stretching or preparing paper and lightweight canvases, offering a stable and breathable surface suitable for sketching, drawing and underpainting with water-based media such as acrylics and tempera. Its natural fibre composition helps moderate moisture exchange and provides a consistent planar support for framing, conservation and mixed-media applications.

Advantages

The cotton construction provides dimensional stability and a uniform texture that reduces local warping when used with paper or thin canvas. Breathable fibres allow controlled moisture transfer, making it suitable as an underlayer for water-based media and for conservation tasks where vapour movement matters. The sheet’s compact 27×33 cm size makes it convenient for studies, small finished works and mounting into standard frames or supports.

Suitable for

• Sketching and pencil or charcoal drawings
• Underpainting with acrylics, tempera or diluted gouache
• Mounting and stretching lightweight papers and canvases
• Preparation of small framed artworks and conservation tasks
• Mixed-media studies and collage base

How to use

Use the cotton backing as a mounting sheet by adhering paper or thin canvas with appropriate archival wheat starch paste, PVA or other recommended adhesives for fine art, following the adhesive manufacturer’s instructions. For stretching, secure the edges to a temporary wooden frame or stretcher bars, keeping even tension to avoid distortion. When using water-based media such as acrylic or tempera, allow each layer to dry thoroughly before additional layers are applied. Handle the sheet with clean hands or gloves to avoid transferring oils or dirt onto the surface.

Usage recommendations

Store the cotton backing flat in a dry, cool environment away from direct sunlight and high humidity. When mounting or conserving works, choose archival adhesives and allow adequate drying time; test compatibility with chosen paints and adhesives on a spare piece before application to finished works.
