Bonnie, I can see the difference since you pressed. Can you? I think you did a great job.
Regarding using the light box. My sewing room is in the basement and when I use my light box, I turn off other lights in the room. See if this helps.
One of the courses I took from Karen Kay Buckley used one of Elly Sienkiewicz's books. The quilt is a Baltimore Album. Can I brag a bit? Karen suggested and I followed, to send my quilt to the Lancaster Quilt Show. I didn't win, nor did I expect to, but it was an honor to be selected to show. It was fun at the show to see other quilts taking a closer look and pictures of my quilt. Some of Elly's books sell for over $100.
