I like how chickadeee55 described it, "a canvas for you to create on". I'm a big fan of cheater cloth and panels, use them for quick gifts etc., but I've never seen anything like this and it took a good long look to realize it's just one piece of fabric. Your quilting is absolutely spectacular. Do you have any idea where it came from or why it was in her closet? Left there by someone who lived there before? You've created a treasure, would love to know more about it.
