I'm not a huge fan of quilts as strictly art. I like art, but I also like to keep things with traditional utilitarian roots as such. I'm a very practical person, and it actually seems wasteful to me to spend all that time and money on something that serves no purpose but to keep the wall warm.
But that's what makes this world wonderful. I'll make beautiful quilts intended to cover a bed, and other people can make beautiful quilts to cover the wall, and we can all look at each other's craft and appreciate it for what it is. We don't have to participate to enjoy. :)
