In the 1st of the above images I initially lay the LED panel on the foamboard to check for fit & mark for length and width. The foamboard I have laid the panel on will become the back panel of the Flat Field panel.
The 2nd image shows the back board with the side & bottom retaining pieces hot glued into place, the LED panel fits very snuggly between the side pieces.
My intention all along was to create a pocket from foamboard that the LED panel slides in to.
