I don't move the laser to line up the next row of quilting. I move the machine. Once I have quilted the first pass across the quilt, (or two passes if the pattern has two passes on it) I cut the thread and move the machine so that the needle is placed at the highest point of the stitching that I just completed (standing at the back or pantograph side of the machine). I insert the needle at that highest place. Then I slowly roll the sandwich up onto the takeup roller (with the needle still inserted in the sandwich ) until the laser light reaches the same position on the pattern that the needle is set at. This position would be on the first pass of the pattern. I then remove the needle from the sandwich, walk the machine along the bottom most position of the pattern watching the needle but not sewing, to make sure that when I start stitching the stitching will not overlap my last stitched roll. Insert the needle at the beginning of my next roll and start stitching.
