I bought the flannel backed plastic by the yard table covering from WalMart, then used a large carpenter's T-square to draw on the flannel side a 3' vertical line with a sharpie. The horizontal line was drawn on about where I thought was best to start putting up blocks. Once I got a reference point, the other blocks lined up. It also works well for on-point settings.

I also drew lines on my clean, just washed ironing board cover to keep from skewing what I was pressing, then ironed the lines to set the ink. Next was to test it with a white scrap to make sure ink didn't transfer to my fabric. My ironing board covers get washed several times a year, and the lines faded a small bit, but still bold enough to use.
