I purchased this and several other introductory stained glass guides. This is by far the best of all of them that I purchased. It is very simple to follow, details common pitfalls and mistakes (for the most part though there are still many tricks of the trade that could've been highlighted better -- black backings for foil, how to hang and install completed panels, etc.) and includes a broad variety of up-to-date project styles. The pictures in the book are great and include projects that are intended to help the beginner build his/her skills -- and NOT as a vanity display of the authors' works (like I have seen in other texts). For me, the book tells probably 90% of what I needed to know to do stained glass-- the rest, as I've discovered, you simply have to figure out by talking with others or trial and error. One major plus for me -- this is an inexpensive book that is well worth its cost.
