Provided for example is a method of forming texture comprising: (I) providing a polymeric layer with first and second sides, wherein the polymeric layer is made from a polymeric material that gels on contact with a gelling agent, and wherein the first side is gelled, with gelling extending into the polymeric layer but not to the second side; (II) contacting the second side of the polymeric layer with a foamy aqueous solution of surfactant (one or more), the aqueous foam being in the process of collapsing during the contacting, wherein the aqueous solution of surfactant is effective to gel the polymeric material; (III) applying a aqueous medium to the second surface with sufficient force or agitation so as to remove a portion of the polymeric material; and (IV) curing the remaining polymeric material without, following the contacting step, further contacting the polymer layer with a gelling component.
