"Knitting for Good!" is a great idea. I've loved the idea of "craftivism" since I first heard it, through Betsy Greer, as a matter of fact. Maybe it's because this isn't a new concept for me, but I found this book to be sort of dry, even though there were personal stories sprinkled throughout the text. It just didn't work for me. Maybe I am not enough of a hardcore knitter.
There are also a few patterns in "Knitting for Good!" but nothing groundbreaking, and nothing I felt like adding to my queue.
All in all: FANTASTIC idea, okay execution, and probably more interesting to people who love reading about knitting or are new to the idea of craftivism.
(My copy was an ARC, and I would give it two-and-a-half stars if goodreads allowed that.)
