I want to vertically tile an image down the left side of the body and vertically tile another image down the right side of the body. I want to accomplish this:

Code:
body
{
	margin: 0;
	
	background: #001e3a;

	height: 100%;
	background-image: url('./left_sidebar.jpg');
	background-position: left top;
	background-repeat: repeat-y;

	background-image: url('./right_sidebar.jpg');
	background-position: right top;
	background-repeat: repeat-y;
}
Obviously, this doesn't work for both sides; only one. Whichever is the latter.

Help appreciated,
