Abstract
A sample pack comprises a piece of sheet material (1) folded to reduce its width by half along its longitudinal axis and then folded again about one or more axes transverse to the longitudinal axis before being rolled about a transverse axis. The longitudinal fold line (2) is slitted at intervals to release pressure in the material to promote folding and rolling. The material is advantageously wallpaper and the sample provides a viable alternative to cumbersome pattern books.
