The Repeatable Dye Batch Book

The ToDye workbook for hitting the same color twice, and knowing what every skein costs

The first batch of a color is a discovery; the second is supposed to be a copy, and often is not. Much of that comes down to one number: our Dye Recipe Calculator says a 100 g skein at a 0.5% depth of shade needs 0.5 g of dye, and a kitchen scale that reads to the nearest gram can be off by half a gram, the whole dose. The Repeatable Dye Batch Book fixes it the way dyers do. Part 1 weighs the fiber dry, sets the depth of shade, shows the weighing error for your scale, makes a stock solution (10 g in a litre: 0.5 g becomes 50 ml), mixes colors by volume and cards every batch. Part 2 costs a single skein, prices it so fees come off before margin, and sells by dye lot. For fiber-reactive and acid dyes on yarn and fabric; not hair, skin or natural-dye mordants. With your purchase comes a personalised sheet worked on the batch you enter in the ToDye calculators.
