By the turn of the 20th century, amateur advisors and publications were increasingly challenging the monopoly that the large retail companies had on interior design. English feminist author Mary Haweis wrote a series of widely read essays in the 1880s in which she derided the eagerness with which aspiring middle-class people furnished their houses according to the rigid models offered to them by the retailers.^[15] She advocated the individual adoption of a particular style, tailor-made to the individual needs and preferences of the customer:”One of my strongest convictions, and one of the first canons of good taste, is that our houses, like the fish’s shell and the bird’s nest, ought to represent our individual taste and habits.

The move toward decoration as a separate artistic profession, unrelated to the manufacturers and retailers, received an impetus with the 1899 formation of the Institute of British Decorators; with John Dibblee Crace as its president, it represented almost 200 decorators around the country.^[16] By 1915, the London Directory listed 127 individuals trading as interior decorators, of which 10 were women. Rhoda and Agnes Garrett were the first women to train professionally as home decorators in 1874. The importance of their work on design was regarded at the time as on a par with that of William Morris. In 1876, their work – Suggestions for House Decoration in Painting, Woodwork and Furniture – spread their ideas on artistic interior design to a wide middle-class audience.^[17]
