Blackout fabric
One pass - "dim out" layer which replaces a loose lining with a better qualityproduct and at considerable cost savings. One pass flocking protects curtain and furnishings from damaging uv rays, insulates the room to keep it cool in summer and warm in winter, and will notitself rot under uv light. Supersoft suede coated curtains are easier and cheaper to make than those with a loose lining.
Two pass - full blackout curtains but the fabric side is darkwith a black layer behind it. Suitable as a loose lining when the dark face is hidden behind a face fabric or can be used on a very dark fabric such as navy blue.
Three pass - full blackout curtains with the black layersandwiched between two off-white layers. This can go on any curtain fabric to make it fully blackout without losing any of its natural colour.
