Afraid I can't help you much, I only make square quilts. Besides the fact that I prefer designing within squares, I find the shape is much more adaptable than a rectangle and looks more like art than like a bed linen.
Squares make perfect wall quilts, no matter what the size, so all mine have a handing sleeve. Squares are also perfect for both queen and king size beds, as well as couch quilts and toddler quilts. Your 60" square redwork would look beautiful as a 'topper' on a queen sized bed, providing warmth for either a cozy nap or a full night's sleep.
