WOW....where is that market? Some of the quilts I have seen here are by fair better than some of those and I am sure "we" couldn't get that kind of money.
But I have seen some of Ricky Tims quilts and they are gorgeous. They are most definitely art quilts and I am sure his work commands similar pricing. I just think his quilts are more challenging that those examples.
