Real Wallpaper! William Morris 'Willow Bough'
William Morris (1839-1896) was the practical romantic who almost single-handedly reinvented the Gothic dream of elegantly decorated everything. His wallpapers are dazzlingly complicated, formal, and of course they tile absolutely seamlessly. The Willow Bough is interesting in that quite a few branches are shown 'clipped': man thus intrudes visually in the leafy effect. Notice also how subtly Morris handles the difficult task of allowing branches to decrease in thickness towards the leaves - while making the branches infinite and continuous!
Morris' patterns are widely used even today for furnishings, curtains, all kinds of gift and greeting card, and, well, wallpaper. Enjoy it!
