With all frames, you typically need to move the machine to one side of the frame or the other in order to change the bobbin. You cannot load a quilt that takes up the entire frame space from left to right; you need to leave at least 10" or so on one side for bobbins. When longarming, I always try to avoid running out of bobbin thread anywhere in the middle of the quilt; I try to change bobbins at the side, even if there is some thread left on the old bobbin. Makes my life easier!
