Depending on how much futzing around you want to do, you can always turn the quilt. Quilt to the middle,(or farther, as much as your roller will hold) then remove the quilt and put it back on the frame, turning it 180 degrees and quilt the other side. You are going to want to roll the un quilted portion on the take up roller and continue quilting from where you left off the first time. The messing around comes from getting all the layers smoothly rolled on the take up. Might want to consider basting with a water soluble thread before you do the second half. It can be done, however, if you are planning on a lot of huge quilts, you may want to look at a larger machine. I know there have been several posts on Baileys. Do a search.
