ABSTRACT OF THE DISCLOSURE Wall coverings of high porosity and having permanent embossing are made by preparing a sheet, e.g. by normal papermaking techniques, from a mixture of 10% - 90% by weight of cellulose fibres, and at least 10% by weight of thermoplastic polymer fibrils (e.g. polyethylene fibrils) having a surface area greater than 1 m2/gm. The sheet is embossed at a temperature below the softening temperature of the thermoplastic polymer. Either before or after the embossing step, the sheet is heated to a temperature equal to or higher than the softening temperature of the thermoplastic polymer.
