I prefer either 505 spray for basting my quilt sandwich or using Hobbs 80/20 fusible batt that you iron to make the quilt sandwich. When quilting he sandwich it is best to start in the middle and quilt out so that any shifting ends up at the edges. If you are using your walking foot to quilt, don't do all the lines sewing the same direction, alternate directions every other row. A great tool for stitching lines is to put painter's tape on the quilt and stitch beside it with your walking foot.
