My boss lent me a magazine to read called View Textile magazine. It is a quarterly magazine that trends forecasts for each of the up and coming three seasons. It covers fabrics, colours, techniques, trends, and also retail reports for the major international cities. It is pretty pricey (the cover says 54 Euro) but I read it cover to cover and learnt so much so I would definitely buy it next time if I can afford it (or steal my bosses!). If you're interested in this sort of thing and can find it then I'd recommend at least having a bit of a flip through.
