Sharon. Great work! You learned something, I got some praise (egotistical little me) and you have a fine block to post on your wall. I see the little mistakes, I call them design elements when I do them. I am not going to tell you how many 1/8 sections I had to make to get this one right also. It is a visual puzzle when you are piecing it together.
If you get more comfortable with the process, there is a fine book out there (Carole Doak?) with 50 star patterns and a dvd video showing you how it all goes together, as well as some great tips on how to make the points all match. You might find someone who wants to give you a X-mass present of this fine book.
You made my day. Thanks.
