I know many of you do your piecing on machines without dual feed or IDT. Do you have any tips on getting accurate feed for piecing? I had a Pfaff 2046, so am used to having IDT, but it had become temperamental so I just replaced it with a Bernina 530. I was piecing some lonnng pieces last night for my quilt back and the top fabric was feeding noticeably slower than the bottom fabric. Is there something I can do to help with this? I was using the straight stitch plate, foot 57, and the standard stitch length (2.4 I think).
