For straight line quilting I start from the centre simply to reduce the amount of quilt in my harp space. I go from the centre out to the edge, turn the quilt around and do the same again. I would rather go from one side to the other...seems more logical but even with the large harp space of the 710, i just can't comfortably fit all of a quilt through. I don't spray baste, have tried 505 numerous times but it never really adheres well to my wool/poly batting and I was getting shifting around of the top whilst quilting. I am now back to my 500 quilting pins and feeling my quilts are more secure.
