Step 5: Pad it out...
Take some polyester batting and lay it on the cutout. I layered about four layers thick so that it has some light transmission and diffusing properties.
You need this fluffy layer to act as the photon transport matrix to spread the light. I guess you could design something similar to a thin LCD panel.

You may want to experiment with your light source to see how thick your padding layer should be. Trim to fit coming to about 1/2 inch short of the edges.
Use duct tape or clear packaging tape to close in the back of this layer. The free edge of the sewn cutout gives you a place to anchor the tape at the edges.
