After assembling my sandwich with 505 Spray, I press both sides with steam. Then, with a basting stitch, run one down the middle, then turn it around and put another down the middle. Then turn around and place basting line hafway between the first basting stitch and the edge, then do the other side . . .then turn around and do it again . . .for a total of three basting lines on each side or a grid of 12 squares.
