These are some of my favorite sewing books currently. Somehow I've lost track of what I used to refer to when I was new to the field. And I will admit that these are references for the intermediate to advance sewist.
Claire Shaeffer's Fabric Sewing Guide is a phenomenal resource. To me, Claire seems to be one of those ageless people who's been around forever. She has the knowledge of an ancient sewist and I have so valued her guides and interpretation. She always references her own research so I feel like I can trust her information. Not only is this book a full resource for fabric identification and handling, it's got comprehensive Appendix charts on stabilizers, interlinings, needle and thread usage. Recommended for the beginner, intermediate or the advanced sewist.
Professional Sewing Techniques for Designers 2nd Edition by Julie Cole & Sharon Czachor is a relatively recent investment for me. I wanted a sewing reference specifically geared to designers so I could check my construction technique and write instructions for sewing my patterns that were based in commonly used, professional method as well as tried, true and tested techniques. I like the way this book is organized and laid out. It's easy to find instructions on whatever you need. I have yet to look something up that isn't in this book. The book communicates the sewing instructions via diagrams and not photographs but I find this, since the diagrams are clear and precise, to be effective. Recommended for the serious sewist, designer and professional alike.

I've found it a useful resource for both sewing and drafting. I appreciate the Sewing Order list as a reference for
