My Cushing's dye sample book arrived this week, and is it wonderful! I ordered it directly from W. Cushing's and Company. Every one of their dyes is done in 6 gradation samples, prepared by Mary Sue Layton. I see now that the book is essential for those of us who dye because with it we can see the colors and determine better what will happen when we mix them. I was told that there are only a limited number of these books left because it has not been determined if and when the dye swatches will be created again! If you are interested in obtaining one for yourself, the book is $75 and can be ordered HERE.
