It's hard to go past the beautifully designed 'Horses Stampede' by renowned artist and designer Florence Broadhurst. The free-flowing nature of this design suits so many styles of interior; great fun in a family room, soothing in a bathroom and dreamlike on a bedroom wall.
'Horse Trellis' by Barneby Gates has a simple geometric feel, finished off with a repetitive horse motif. Horse themed in a more subtle way then some of the other examples - this wallpaper comes across as a very 'grown up' design from afar, but quirky in nature up close, and the yellow and grey colour way is quite stunning!
