Someone here gave this link the other day. These are the printed tops, only - various sizes:

These are queen size, printed top, backing fabric and binding kits:

They're the same basic designs, but quiltingstencils.com carries smaller sizes and sells the printed tops without the backing fabric.
I think it would be nice to put a beautiful print on the back - but then the quilting won't show as much on the back as if it were a solid color. I think there's at least one wholecloth kit in my future, but I can't decide which one. :)
