This is why I think it's a matter of personal preference. For a wallhanging I would know what the back looks like even if no one else ever sees it, so it would bug me if I didn't do something nice with it. But not everyone feels that way. Just how some people prefer coordinating really matchy fabrics for their tops and some people like everything but the kitchen sink scrap quilts.
