I went to marks and spencers today and left with a material swatch for every suite they sell with cleaning instructions on the back (For free they hang them up for customers). I just thought i'd mention it as although i've done upholstery cleaning courses it can sometimes be hard to identify the fibre content of the suite. ( On the back of the swatches it also lists the % content of each material) Asked the store manager nicely and he's sending me a swatch book of every fabric they have sold.
