This book is wonderful. Since I received and read it, I have taken a lampworking class. I must say I am hooked. Since the class I have re-read this book over and over again. What I did in class was very close to explanations in the book that were perfect. I can't wait until I have the space that I can make glass beads at my home. This is a wonderful book, anyone who is interested in making glass beads should have this book. Thanks again to the seller. Brenda
