Quilt for auction...top finished

I decided to donate a quilt to D'Angela and Kyles's adult handicapped group, Among Friends, for their fundraiser dinner and silent auction which will take place sometime in April. I chose a simple pattern, Tessellating Pinwheels, by Gayle Bong and purchased O.U. fabrics. I did change the pattern by using a different fabric for the inner border. This pattern went together very quickly with strip piecing method. Top is now finished and I have to decide on a quilting design. I'm thinking an allover pattern. Maybe freehand fans or meandering swirls of some sort. Should I go with red thread or white or...??? Finished quilt size will be 64" x 80". Nice size for a twin bed or cuddling up under at a football game.
