I would use a dark narrow border next to the quilt to "frame" it, then a larger outer border in a lighter fabric. Of the three you auditioned I would use the blue with stars and the green solid.
Lay out the green solid, put the blue over it leaving a good 4" of the green showing in a corner, then lay your quilt over the blue with about 1" showing - again on a corner. Stand back and take a look.
