Thanks for all the quick replies. I have it loaded up and plan to try it tomorrow (Saturday). I should have specified that I plan to take the pins out of the section I am quilting as I go. I left the pins in just to keep everything sandwiched correctly.

I had to go over the backing rail because that's the rail that is parallel to the take-up rail. The sandwich wouldn't be level and couldn't be quilted if I didn't use the backing rail.
