your quilt is stunning. For someone who has only been quilting for 5 years, I think you did a great job of making that quilt. Unfortunately, once your customer saw some of those thread tails.....she turned her attention into fine detail and looking for every imperfection she could find. I'm sorry you have to deal with this, but all the experienced ladies on this board seem to have provided great guidance. It's a great learning experience for us all (even the binding thing by sewing the corners), but also an inspiration for me....what's that pattern? Looks beautiful, but hard.
