Here are some photos from my pavillion this year:
In the top photo you see the headboard of the bed, and while not glaringly non-medieval I still wanted to make it fit in more with the rest of the furniture, and with period images of beds.
Especially since a lot of people now have bought the same beds.
So glued some 1mm plywood on to two of the bars, making it look like a whole board there, and stained the whole bed with the same paint as the chests. I also painted our devices and some patterns on the "board" of plywood, and added two wooden knobs that I had painted.
I think it will look really nice when we camp next time.
