I know it is new and still looks a bit staged. I wanted to spread out the hair grass, but I have little patience and it is so hard to plant, I just left it in one clump.
The Foam Core handles the heat of two 9 watts well (cool to the touch inside and NO heat on the outside). It does not handle repeated foldings well: there are places where the black on the outside shows the folding. This hood was a test, and so far it is holding up. If it continues to perform well, I will redo it (this time using a straight edge).
