I find working in a small area easier than going across a quilt numerous times - that's too much pushing and pulling for me. I flatten an area under the arm, FMQ it and move on to a new area - maybe 10 inches square. I always turn the quilt as needed so that more than half the quilt is not under the arm. Center to edge, turn, center to edge, turn, etc. My QOV are twin size and it hasn't been a problem. I am a puddle and pusher, not roller.
