I looked for a book like this for some time. I already have some experience with making cushions and curtains and I like to explore and learn more by being self-taught.
In this book I particularly like the explanation of the sundry materials (lining and interlining), types of threads and their use, types of tracks, poles, baten systems. There are a lot of useful tips, clear steps with pictures and you know exactly what you are doing without feeling stuck as I did with some other books. And I wish I had this book when I was joining piping together (flanged cords) for this first time, the book makes it so easy to understand. Also, this is the first book I've come across that shows how to make a firm pelmet using plywood.
This book is worth buying, it is written with care.
