One customer which will forever remain nameless, covered the fire bowl when it was still hot, and the marine fabric was damaged. When he came to pick up a new cover, he told me that he was surprised that the cover was not fire resistant. He almost managed to keep a straight face, I couldn’t, I started laughing, and he joined in.
I did add another common sense warning though. Make sure the fire bowl, glass and burner are completely cool when you cover the bowl.
