What do you use for background?

On most of my tanks, the backs are covered with a black garbage bag.

On one of my 20 gallons, I use a laminated Playboy centerfold, a horizontal one...Christina Leanardi. :D
 
I used black poster board on my tank and it came out well. It was also very inexpensive at $2 for 2 sheets. I bought some double sided mounting tape and it's holding nice and solid.

Thanks, everyone, for the replies. I finally got around to painting mine black and I LOVE IT! The cardinal tetras used to really blend into the blue background I was using. Now they look like neon lights. It's a great effect, and I'm really glad I did it. I pulled the tank away from the wall during a water change, and painted it with a flat black enamel paint and a small roller.
THANKS!
:D :D :D

I also prefer the color contrasts that seem to really come through with black backgrounds. I used the LFS black plastic and used cooking oil, or Pam (cooking spray) and it worked out great! I forgot who exactly gave me the advice, but it was here on AC..
