Aren't Velux blankets the ones that feel sorta spongy? I have a Martha Stewart one in blue.

FWIW, years ago we had a waterbed and we had a black satin spread. I never thought of it being kinky at all. Just so happens our room was decorated in black and gold. Can't remember the color of the sheets.

Also, wasn't there a sheet of black metal taken from the Ramsey basement? Did we ever find out what that was all about?
