book I have drawn largely upon these sources of dyeing knowledge, as

well as upon the traditions still followed by present workers, and upon the experience of my own work.

All dyeing recipes, however, should guide rather than rule the worker; they are better applied with imagination and experience than with the slavishness of minute imitation. Every dyer should keep a record of his experiments, for this will become invaluable as it grows, and as one thing is learnt from another. The ideal way of working is not by a too rigid accuracy nor by loose guess-work, but by the way which practice has proved best: nevertheless, some of the greatest dyers have done their work by rule-of-thumb methods just as others have certainly worked with systematic exactness.

The dyer, like any other artist, is free to find his own methods, subject to the requirements of good and permanent craftsmanship, provided that he achieves the effects at which he aims. But it is supremely important that he should aim at the right effects; or, rather, at the use of the right materials, for if these are right the effects may safely be left to take care of themselves. In order to develop the taste and temperament of a good colourist, it is necessary to use good colour and to live with good colour. In this book I attempt to show where good colour can be obtained. But one may begin to live with good colour which has been found by others.

This part of the dyer's education is not prohibitively costly, even in these days of inferior colour. Indian and Persian embroideries are still to be obtained, though care must be taken in their selection, as most modern pieces are dyed with chemical dyes and are very ugly. Persian Khelim rugs are cheap and often of the most beautiful colours. Russian embroideries and woven stuffs, both old and new, are obtainable, and are good in colour, as are most of the embroideries and weavings of Eastern Europe and the East. What are popularly known as "coffee towels" are often embroidered in the finest coloured silks. Bokhara rugs and embroideries are still to be purchased, and many of the weavings of the far East, although, alas, very few of the modern ones are of good colour. I would say to dyers, do not be satisfied with seeing beautiful coloured stuffs in museums. It is possible still to get them, and to live with a piece of good colour is of much more use than occasional hours spent in museums.
