My old Viking D1 allows me to program my own stitch so since I didn't feel the 1/4" foot gave me the scant 1/4" I wanted I made my old and use the foot with the flange on the right side. Seems to work fine for me. Love my old D1 so much for piecing but its screen is starting to fail so will have to take her in for a new one or if too expensive to replace then find another Viking that can use all the numerous feet I have for it. This Viking machine has been a trooper since I got it back in 2000. Have made all my quilts with it, clothing and even stitched over 8 layers of blue jean fabric. Not too many machines can do that. Don't think I'd want to do it too often though.
