You can " birth or pillowcase" the quilt. Lay your backing on top of the quilt top and sew all around. You can leave a section open on the edge to turn but you might not get a nice round edge where it is left open. I might sew around the whole edge and decide where I will put a nice big label on the back. Slit the backing where the label will go over and turn the quilt through the slit.
