yes, you are making perfect sense, and wish I knew the answer. Like Amma said, you roll the parts of the quilt up, to the area your working on, and you need a higher space to accommodate a big 'roll'.
Think I have paid more attention to the amount of space under the presser foot, but this is important too.
ok, somebody has info on this...come out, come out, wherever you are...well, if you need a bath first...we'll wait :mrgreen:
