I did a session this past week for Brother's Innovis Dream machine and completed the survey. My quilt guild benefits from it and the shop hopes to sell a few out of the sessions. Anyway, our educator for the machine talked about the sideways stitch being helpful when you do totes or purses and you want to put that X on the square near the handle. You could stitch straight, then sideways and then even diagonally without twisting and turning your piece or raising the presser foot.
