Reddit mentions of Knitting Pattern Essentials: Adapting and Drafting Knitting Patterns for Great Knitwear

I very much like Knitting Pattern Essentials by Sally Melville for understanding sweater fit and patterns. However I believe she mostly addresses women’s wear (I don’t have it with me so I can’t check right now). Ignore the included patterns. I do think many concepts are transferable to menswear (e.g. how different shoulder styles make your shoulders appear wider/narrower etc). As long as you already understand what looks good on your own body, I think this book could be a good reference for working with sweater patterns.

Knits at Home has some seriously gorgeous knitty home stuff, super easy to make and she explains the process so you can properly get a handle on what works and how to tweak it to your taste.
Sally Melville's Knitting Pattern Essentials is an awesome learn-stuff book if you want to know how patterns work (and therefore how to adapt them to what you want and make them fit). Some nice patterns too.
I'm putting Alana Dakos's two Botanical Knits books and Cirilia Rose's brand new Magpies, Nomads and Homebodies on my own Christmas list cuz they both look so darn pretty (and fun in the second case!) but I haven't actually read them yet. :)
