To avoid your decor scheme becoming overwhelming, remember the "wall-floor" rule. If you've used a distinctive wallpaper, make sure that your floors or rugs are textured plains -- using the same base colour to co-ordinate the look. The reverse goes for detailed carpets or rugs, in which case your walls should be plain. If you're dead-set on hanging wallpaper, rather opt for textured papers like "Drop Seed Hessian" Wallpaper from Hertex (R1100 per roll)
