I can't wait to get the book! Would you say that your new book covers a lot of the processing in relevant ways that other books don't cover? for example, there is a book written by the brothers at the Hermitage which I've always eyed but haven't had the opportunity to read.
and then for spinning, these are the books i have:
Linen Handspinning and Weaving, by Baines
Handspinning Flax, by Olive and Harry Linder
Spinning and Weaving for Softness & Speed, by Paula Simmons
The Practical Spinner's Guide - Cotton, Fox, Hemp, by Gaustad
