I have a similarly designed quilt, with blocks like yours, that I am deciding how to quilt. I have read quilting guidelines that suggest if the quilt blocks are mostly straight or angular rather than curved, that it is good to quilt in curves. Vice versa...for curved designed blocks, you could use straight lines to quilt. Having said that and wanting to use my walking foot on this one, I reviewed the petit design link and I am opting for Orange Peel or Giant Clam Shell. (Of course the curved lines and curved grids are easier, but not as much pizazz). After looking at them all, those two would have the least pivoting for the lap size quilt I am doing than the other designs. Of course, one could free motion and that would minimize the dreaded pivots. But the goal for this donated quilt is speed and I think the walking foot will accomplish that. Those are my thoughts. Hope it helps.
