If you want to find the next trend for interiors then try looking at high end fashion magazines. I find that Vogue magazine is always a great source of reference. Fashion trends always transcend into interiors trends.

If you take a look at Vogues website they have a great section on the ‘hot trends’ for that season That section will give you a good guide of the type of colours and patterns you can expect to see coming through into interiors about 6 months later.
