I really like the quilt and the quilting. We are our own worst critics. You are looking at such a small area and thinking everyone will do the same. They won't. If you didn't have the lines there showing where you thought you were going to quilt, no one could tell that any error had been made. I would not rip. If you wash it before you give it to her, I am assuming the lines will wash out, it will continue to be just beautiful.
I love that quilt pattern. Would you share the name?
