Backdrops

Now, I've been up for 20 hours and playing World of Warcraft for too many of those hours, so I'm a little brain fried, but I'm sitting there shooting people in Warsong Gulch when a thought comes to me... When people say stuff like "Go to Home Depot or Lowe's and get a backdrop from there" are they talking about a painter's drop cloth, or what? Because I want to get one, but am not sure what people are talking about. If it's the drop cloth, I have 2 already (paint freak for a wife)...

Thanks in advance.

What color backdrop do you want? For the DIY, I would visit your local fabric store and buy Muslin. It only comes in white and off white but can be easily dyed to any color.

I wanted more of a blue. I'll check the local fabric store today. Thanks!
