While you are creating your fabric scheme think where each fabric will go. Every fabric sample will have a label at the back that will show if that particular fabric is suitable for the window treatment and or upholstery too.
Also look at the fabric composition and how many rubs is indicated. To be able to understand the later is important in order to see the durability and suitability of a fabric. Sometimes you will find some little icons or other time a rub number given by the Martindale test. The rubs number will indicate if a fabric is suitable for decorative purposes only, usually then less than 10,000 rubs, for light domestic, 10,000 to 15,000 rubs or general domestic, 15,000 to 25,000 rubs. If you need fabric for heavy duty then you have to look at 25,000 to 30,000 rubs.
