Hi,
Perhaps I can help you with your enlargement issues. I've never posted anything so I hope I can show you what I mean.
Remember that a copy enlarges both directions. If your image is 25% of what you want to end up with, a 200% enlargement will get you where you want to go. For example, a 2"x2" image is 4 sq inches. When you enlarge it 200%, it becomes a 4"x4" image (16 square inches). The original 2x2 is 1/4 of the new image.
I know it doesn't seem to make sense, so I am going to try to attach an example.
Good quilting.
