If you move the needle on a machine, you use the regular foot, not the 1/4" The regular foot for any machine usually covers all of the feed dogs so you get more traction on what you are sewing. I had a Rose, and did move the needle for certain applications.

I did some mini quilts years ago with a Pfaff 1475. That uses a 9mm foot, and to get a 1/8" seam (required) I had to mark and switch the needle position to get it using a 9mm foot. If I didn't, there wouldn't have been enough material to use the feed dogs properly.

I will also use an open toe foot on the PQ1500 so I can see where I'm going, rather than a STID foot.
