I had more than I needed, so I'm selling the extra fabric. No extensions. Fabric width: approximately 110cm x 100cm Pre-washing: Unknown. I'm not sure if I pre-washed it all and had it ready, or if I stored it as is after purchase. Please understand that this is cut by an amateur and may have fold lines. Will be folded compactly. #n fabrics USA Cotton Flowers Scraps Seersucker Extra Riley Blake
