Description
7 oz 54" Heavy Flannel Cotton Interlining Fabric for Curtains & Draperies
Our Cotton Interlining Fabric is Napped on Both Sides & specially engineered for curtains, draperies, and window treatments that need added structure, insulation, and a fuller, more luxurious drape. Soft, durable, and easy to sew—perfect for both professional workrooms and DIY home décor projects.
Transform your window treatments with this premium interlining designed to enhance the structure, body, and thermal performance of drapes. This mid-weight cotton layer sits between the face fabric and the lining, giving panels a more elegant hang while providing improved insulation, light control, and sound absorption.
The generous 54-inch width reduces seaming and is ideal for large drapery panels, commercial workrooms, and custom installations. It pairs beautifully with our selections of cotton canvas, natural linen, and decor-weight fabrics to create professional-grade curtains, roman shades, valances, and more.
Big Duck Canvas offers wholesale pricing, fast shipping, and consistently dependable workroom-quality textiles for sewing and manufacturing projects.
