Voysey for his wallpaper at Liberty's, who felt that the underlying aesthetic of Japanese workmanship must first be understood to create an independent Anglo-Japanese work, and that to try to reproduce it when solely aesthetical purpose and outside tradition would pragmatically create superficial work. Speaking in 1917, comparing his abhorrence of the many poor contemporaneous imitations and 'traditional Japanese' works to 18th century English Chinoiserie Japanning furniture, he noted that although "we may fitly imitate in an object of our own, the finish we find in Japanese workmanship, but the imitation of its traditional thought and feeling is absurd, Chippendale exhibited this kind of [visual] absurdity when he produced his Chinese furniture". Interior Design In the design of furniture, the most common and characteristic features are refined lines and nature motifs such as 'Mons', and most particularly an ebonized finish (or even ebony) echoing the well known 'japanned' finish. Halen (p. 69) proposes an ebonized chair exhibited at the 1862 International Exhibition by A.F.

The types of furniture required in England such as wardrobes, sideboards and even dining-tables and easy-chairs did not have a Japanese precedent therefore Japanese principles and motifs had to be adapted to existing types in order to meet English requirements. Dresser noted that the 'Mons' of Japanese Art also have their similarities in Celtic 'rudimentary art'. Architecture Many British designers of the Victorian period were taught the Neo-gothic design principles of John Ruskin and Owen Jones, principally the Grammar of Ornament (1856), which did not include Japan. 'Ornament' referring to an important aspect of English architectural decorative design for the period, deriving from the popular ornamentation at the time found on the exterior of European churches, and placing this beside nature. Yet by 1879, it was reported that ornamental gothic 'natural forms [had] all the nature flattened out of them, [being] arbitrarily and mechanically arranged', and thus for satisfactorily replacing the Ornament of Owen Jones, Japanese art had 'taught [the British architect] the lesson we wanted, in teaching us how to adapt natural forms without taking the nature out of them. Gothic art showed us something of this; but it did not show it so clearly, nor in so many ways, as Japanese [art
