I've been sewing for over 30 years, & I still turn to this book as a way of either improving on old methods or simplifying them in some way. I've gotten books over the years that never seem to have my particular question. This book ALWAYS does. It is easy to understand, the illustrations are clear. It shows each method the "conventional" way AND the Overlock way. The section on fabrics is pretty good, although if you want a more comprehensive book, look for Sandra Betzina's book on Fabric Saavy. If I were learning to sew & could only have one book, I'd go with this one. I would highly recommend the Spiral binding as it lets the book lie flat--important if you're working while using it.
