Conforming a layer of porous sheet material having a three-dimensionally patterned exterior surface, the material being applied directly on a smooth base member made of plastic, metal, glass, etc., and then applying a coating of a hard-enable film-forming liquid in an amount just sufficient to cover the "hills" of the patterned material and seal its pores, but not to fill the "valleys" of the material when hardened. As a result, contours of the pattern are not obscured. The desired pattern may be the inherent weave (interlaced threads) of a textile or an ornamental design embossed in a non-woven material, or the like. Penetration of the film-forming liquid through the pores and into the interface between the fabric and base member partially adheres the fabric to that member upon application of the liquid, an adherence only completed upon hardening, so that interim adjustment in positioning is provided.
Method of producing a textured finish on a given area of a smooth support member, comprising the steps of:
