I was quite surprised to find that there are actually some very attractive designs in this book - stained glass patterns can sometimes look awful, and the cover illustration does not do it justice. For a book published in 1985, these designs look reasonably contemporary, or perhaps timeless would be a better description.
There are two or three where the design is suspect, but that could be a matter of my personal taste.
The good things about this book, in my opinion, are:
Mostly attractive designs. Full-sized templates which should help when assessing how much glass you need, and how the design should actually look. (The full-sized templates also help to decide whether the shapes are easily cuttable or not, unlike small patterns which look fine until you enlarge them and find they are virtually impossible). Printed on good quality paper.
Bad things are:
VERY minimal instructions. The book tells you how to cut out the shapes from the pages to use as templates, which is hardly rocket science. (If you don't want to cut up your book, trace off the designs onto a good quality cartridge paper, using a window as a light box. This is what I do, it doesn't come from the book).
There is nothing to help you to work out how much glass you need, other than presumably physically taking your pattern pieces with you when you buy the glass. There is no advice on which type of glass would work best for a particular design.
The important finishing touch - putting the mirror in the frame, is only touched upon very briefly, and is not helpful. The 'clear instructions' promised in the blurb are very very basic. 'Either cut the mirror to fit within the borders of the stained glass, so the final product is all one flat plain, or else you can place the mirror beneath the frame, so the final product has a raised border.'
Thant's it.
The 'dozens of compositions' promised in the blurb is quite an exaggeration. There are 16, and if you want more, you will have to take parts of one design and incorporate it into another.
This is basically a book of full-sized patterns, mostly attractive, others less so. It does not take you step by step through the making process, no cutting or copper foiling advice included - which experienced glass workers would not need anyway, but a little more general instruction would have been welcome.
Worth having if mirrors are your thing, and you have a little previous experience in stained glass.
