While extra wide fabrics can seem more expensive, when simply looking at the price per metre. They are usually much better value if you work out the cost per metre at a standard width of fabric. So a £30/m double width fabric is actually only £15/m if you are comparing it to standard width fabric.
They can also save both time and money for made to measure curtain or roman blind projects. Plus, the seamless finish adds a touch of luxury to your interiors — one reason why designers often prefer it for high-end curtain fabrics.
