machine quilting away

This is what it looks like with me trying to wrestle a queen sized quilt under my machine at midnight. Surprisingly, its coming out pretty well! Ive never machine quilted anything larger than a pot holder before so keeping the beast under control is my biggest challenge. I thought I would be able to get away with not marking all of the lines on the quilt, but so far that seems very unlikely. The thing is so big and heavy that it steers itself all over the place and I loose track very quickly of where my straight line should go. The chalk clicker and the tailors chalk are definitely my friends...
