I have chosen perfect binding for my lookbook. I feel it is the most appropriate for its use. Binding that uses visible stitching would not fit in with the brief of being sleek and elegant for Harvey Nichols. Perfect binding would enable a smooth finish. It is also a form of binding I have not yet tried, so I am also trying to test myself in this area further.
Perfect binding is not one of the strongest types of binding, however the look book will be changed quarterly and therefore wouldn't need to withstand years of use.
Below is a short tutorial on how to perfect bookbind.
