I learned this lesson when I switched from a gauge presser foot which I could SET for a scant 1/4 inch seam and purchased a piecing foot (with built in guide)which makes the seam just a stitch width bigger. I only use the piecing foot now as I can just let the feed dogs pull the fabric through right up against the little guide. I use an old Singer 201 which has a wonderful stitch and really performs. PS I have a brother too, which I only embroider on. Just give me a vintage Singer ANY DAY!
