I bought that book, I ended up not liking the look of the seams.....
The idea is great.. Who wouldn't want to have their quilt finished when you're finished?
There's another similar technique, I don't remember who I saw demonstrate it.... you quilt in sections, join the sections, and quilt over the seams, that's more to my liking.
By the way, I gave the book to a co-worker, she loves it.
