This is a comprehensive learn to sew book but there wasn't really anything new.
It has a section on body measuring, which is good, but it does not cover fitting a pattern using the measurements - sure, that's not beginner level sewing, but it feels like half a sentence. And, yes, you can use the skills in this book to personalise, upcycle and repurpose clothes but there are no examples to inspire you.
If you don't know how to sew, this is for you. But if you already have a basic sewing instruction book and you have developing skills there's not that much additional information here for you.
