A. Sharon,
We will typically conceal the additional ribbons within the matting of the frame. We like to show enough, to capture the obvious, but it is not necessary to show the entire length.
As with all shadow box frames, we attempt to let the presentation tell a complete story, so we want to incorporate other elements in addition to the medals. Pictures of the person who was awarded the medals as well as other supportive collateral material.
Regards,
