if you say nothing the person is left feeling very poorly, wondering, embarassed that something is not right, but, what is it? I think that is awful too. Perhaps one could say..you have really worked hard. If I were to try out that design, I would love to use these colors. I have even made the same design several times trying out different ideas and techniques. It was a fun learning session....or I remember how when I started out to quilt that I watched you tube videos to pick up hints. Have you ever had the fun of that? After making a few quilts trying out suggestions, I took classes that could help me focus on improving. Quilting is an endless opportunity to learn about color, technique, design. Don't you just love the challenge. You are never bored.
