Query: Very Technical & No real recipes for home dyers

I have this book and it is good but very technical - and the recipes are very general 4% of dye stuff to fibers dyeing etc, for which you'd need a scale...uses lots of metric calculations as well...it does give you a lot of information on a lot of different dye materials. I wouldn't recommend it for the home dyer.
