Has anyone ever made one?

I'm working on one that was intended to be finished when Sam was born... 4 months later I'm down to three and a half panels left to stitch.

The reason I'm wondering if anyone has ever done one is because I'm after some advice on how to finish it off. The fringing around the outside edge should be fine - but what about covering the back of the stitched panels? Should I? If so, how?
