For the five decades of their partnership, sisters Susan Collier and Sarah Campbell were at the forefront of textile design, with their vibrant hand-painted patterns. They first made their names with stunning collections for Liberty of London Prints and, endlessly inventive, their work has been taken up by fashion leaders including Yves Saint Laurent and Jaegar and major homeware producers, like Habitat, Martex and Stevens, Fishbacher and P Kaufmann. Today, their collections of prints and patterns continue to be in great demand on the vintage markets. Totalling over 30,000 pieces, the Collier Campbell archive holds roughs and sketches, colourways and printers gams, fabric and wallpaper samples, clothing and diverse items bearing their designs. Susan and Sarah were renowned for their handling of colour, painterly approach and signature ability to cheat the repeat in printing: qualities that infuse their work with a sense of fluidity, freshness and exuberance. This book presents hundreds of their designs many instantly recognisable which will form an essential reference for designers, fashionistas and students alike. With exclusive commentary from Sarah, quotes from the late Susan, and the voices of key collaborators and experts in the field, this beautiful collection will cement their reputation as one of the key creative partnerships in modern design.
