Abstract
A flexible wallcovering is made by applying a foamable composition (13) to a woodchip paper (12, 14) having woodchips defining a relief surface on the paper by a screen printing process and then foaming the composition. Preferably, the wallcovering is of two ply construction with a woodchip content between the plies and the paper is formulated so that the upper ply is dry removable from the lower ply. The woodchips are at least 2 mm in average length; and the woodchips form 20 to 35% by weight of the paper.
