I would ponder making him a quilt but I would also bring him in on the process if I could. Allow him to experience picking patterns, colors, cutting and relate this to a skill that he has such as auto repair, building, plumbing, dirt bike racing, hunting or such. He is showing you that he has preferences, not your aunt's quilt, but he likes your work. Use this time to teach him how some of the knowledge and skills are involved in quilting. I guess in teacher lingo this is a "teachable moment". Don't allow him to continue in his "stupidity" help him to understand the value of your quilt as well as the quilting of others even if we don't like their work we can still value their work. He doesn't need to learn HOW to quilt but learning ABOUT the quilting process could add even more value to your work in his eyes.
