Matching Gütermann Sew All Thread
Neptune is a bold, deep ocean blue blackout lining that brings a rich pop of colour to your curtain projects. With a white reverse and saturated woven front, it’s both practical and striking, ideal when you want your lining to add to the overall look, not hide behind it.
Woven from a durable polyester-cotton blend, this 3-pass blackout fabric offers full light protection, flame retardancy, thermal insulation, and even some noise-reducing benefits. It’s got a smooth, structured handle that gives your curtains extra body helping them hang beautifully while adding a more luxurious finish.
Perfect for use as a traditional lining or as a standalone curtain fabric in smaller spaces like caravans, boats, or home offices. We also love it for bedrooms or nurseries where you want to reduce light in the evenings without sacrificing style.
