After I began taking a stained glass class, I ran to the library and the bookstore. My instructor is good, but he's only one opinion. I must have looked at a dozen books, but this is one of the two that I brought home. I'm certainly glad I did.
Like many such books, there are three sections: basic techiques, projects, and a gallery that shows what you can do (but offers no instruction -- just an ooh-ahh opportunity).
The techniques section is among the best I've encountered. In a sense, the info that beginners need is all about the same: the supplies you need, the types of glass available, etc. However, Creative Stained Glass always seems to have just a little more info that do the other books... maybe it's just four paragraphs about the kinds of solder instead of two, but at this point you need all the info you can get.
That first section is 40 pages, which is more than most books devote to the basics. The writing is friendly, too.
In addition, the projects are pretty! I've seen far too many stained glass books in which half the projects are, well, lame. The glass equivalent of a crying clown painted on velvet. The projects are more likely to be leaded rather than to use copper foil; most beginner books seem to choose copper. Each project has about three pages of instruction, plus the patter; my one quibble is that it often doesn't tell you by how much to enlarge the pattern.
I'm not positive I could have learned stained glass wholly from this or any book (this is one area in which a hands-on class makes all the difference), but this one would have given me the most confidence.
Overall, I've gotten the best advice from this book. I'm glad it's in my library. You should probably grab a copy, too.
