Hi Mel!
Welcome to the board!
You have a good book to start with! I had that book when I first started making quilts also.
My advice is that you take a beginning quilting class, so you get the basics down and hear lots of good advice. Even if you have taught yourself from books and magazines, one beginning class is very worthwhile.
My other comment is that you can't add a border to this quilt unless you are going to pick out the quilting, unbaste it and get a larger piece of batting and backing to fit the larger size the top will become.
Hope this is helpful and that you post pics of your quilts here in the Pictures section of the board when they are done.
