i stay stitch as i go.
i load the backing on the rods, then i float the batting and the top by doing stay stitching along the top edge a 1/4 inch in.
then as i work from the top to the bottom of the quilt i will do stay stitching along the side also a 1/4 inch in.
then when i'm done quilting that area i'll roll the quilt to the next section and do stay stitching as above.
