Jeanie, you don't need the book when you have the software. But I'm like QuiltE, I love books, reading them, looking at the pictures which is helpful because I'm trying to follow Jane's original colors. And I use it as some kind of diary, writing the date I finish a block with a few short lines about what happened that day.
And like QuiltE, looking at how many blocks I still have to do I also say 'What was I thinking'...
