Picked up some fake gold leaf a.k.a gold foil from work. You can see a pad of it in the image below. The seraphim are surrounded by a fiery light so bright that nothing, not even other angelic beings, can look upon them. The name Seraphim means "the burning ones."
I would have liked to use real gold leaf but apparently it is hundreds of dollars for a few small sheets. Maybe next time. I showed the above image to my favorite teller at the bank and she said "Is that cheese?"
