This is the perfect size for a lap robe... it can drape across the sofa in the day time, a nice wrap while reading or watching TV in the evening, an extra layer on those cold winter nights. Since it is already a "fussy" print I think your best bet would be to quilt by outlining the design already in the quilt. You could make two of them and back each one with a color you think would be enhancing or complimenting.... Actually this would be best because it is very hard to match up sewing lines on both sides precisely.
Have fun!
