Union Jack Quilt - Backing

I swear, she was dead asleep in another room but the minute I put this on the spare bed she magically appeared.  

A close up of the backing, featuring a tail.

The backing for the Union Jack Quilt is complete and consists of several prints from Lizzy House's Castle Peeps collection.  I thought it would be cute to feature the castles on the Union Jack Quilt and I like how it turned out.  The hard part will be to keep this somewhat centered when I quilt this.  But, I'm not above saying I wanted it off center and that's why it's quilted that way.
