I have the one my mom had that was published in 1979! I like it. I pulled it out on Friday and was thumbing through and saw the section on blackwork. I bought a picture of a dragon that is done in blackwork but couldn't figure out how to start it. Now I have a guide.
Perhaps I'll use it to teach my Girl Scout troop how to do various needlework including knitting and crochet.
They can earn a patch for learning it.
