On a quilt top I realize that some "fudging" can be made, but how much? I am machine quilting on a stack and whack. I am using a Kenmore, which is working well, however, the queen sized quilt is challenge for this newbie to manoeuver. The blocks are on point with a 1 inch sashing. I stitched in the ditch around the center blocks, then did somefree motion on each pinwheel in the block. The farther out towards the outer edge, it seems that the top has stretched, even inside some of the ditched blocks. Is there a quilting pattern that more easily hides excess fabric-"quilt it out"
