I felt your pain just reading your post and my heart goes out to you. I could never imagine getting a rejection like that from someone as close to me as a parent. I am so sorry he didn't appreciate the effort and gesture after you tried so hard and gave him your very first quilt, which looks great and very patriotic to me.
Blame it on "old" age and keep quilting. At least you have a supportive hubby and an accuquilt :)
