Knit Wear Love: Foolproof Instructions for Knitting Your Best-Fitting… by Amy Herzog
I really loved the idea of Amy Herzog's Knit to Flatter book, which is about finding and adjusting patterns to suit you. It's a great book (from what I can tell without actually following any of the patterns since I just had it from the library for 3 weeks), but I found that the patterns didn't inspire me, so it hasn't gone on the list of things I want for my personal knitting reference library.
Knit Wear Love has solved this problem for me: rather than focusing on body type, the designs are more heavily focused on aesthetic: classic, sporty, bohemian, etc. She's got some really cute details, and it's showcased by lovely photography. Plus, of course, huge numbers of charts, advice about fit, etc. It's pretty much everything I wanted in a sweater book. I borrowed a copy from the library to check it out, but this one is going on my personal library wishlist for when I'm interested in tackling a sweater for myself.
