A method of treating a woven fabric to produce a stretchable fabric combination which comprises applying heat and pressure to the fabric in such a manner that the yarn strands substantially across the width of the fabric ar e forced closer together thus imparting generally semi-permanent stretch into the fabric while simultaneously at least partially bonding thereto a synthet ic interlining fabric employing a stretchable bonding agent or film. The woven fabric employed in the method of the invention will usually be of a non- synthetic textile material, for example wool or cotton, which can not normal ly be permanently set by heat alone. By contrast, the interlining material will normally be a synthetic material which is thermoplastic and can be heat set, such as a polyester or polyamide textile material. The bonding coating or fi lm is preferably material which as well as bonding will impart stretch to the final combined product and it is preferred for this purpose to use a polyurethane material. The material may be coated on either the woven non- synthetic fabric or the interlining fabric or may be a film interposed betwe en the two.
