 The "Grammar of Ornament" was particularly influential, liberally distributed as a student prize and running into nine reprints by 1910.Jones declared that ornament "must be secondary to the thing decorated", that there must be "fitness in the ornament to the thing ornamented", and that wallpapers and carpets must not have any patterns "suggestive of anything but a level or plain".A fabric or wallpaper in the Great Exhibition might be decorated with a natural motif made to look as real as possible, whereas these writers advocated flat and simplified natural motifs.
