I'm curious about how your brother feels about music created on a synthesizer. My husband has one and enjoys it, and I kid him that it's fake music!
Clearly, the 'methodogy' argument applies in almost ever aspect of our lives. I love and treasure hand crafted quilts, but hand quilting is beyond my ability for a number of reasons. So I have a computerized quilting system, and I do what I do. My quilting is not perfect by a long shot and I have found that using the same quilting pattern on two different quilts yields different results. Let's just say that perfection is not in my quilting vocabulary!
However, I'm ok with that because without my computerized system, none of my quilts would be quilted. I'd just have a bunch of tops sitting in a closet, and they'd probably wind up at Goodwill after I died.
I have made my own quilting motifs/designs, but, honestly it's a ton of work. I'm retired and decided I didn't want to work that hard, so now I buy patterns.
However, most of my quilt tops are made without benefit of a pattern. That's where the real fun of quilting is for me!
