Explain how to get a 1/4" seam out of the machine for sale and that would be enough for me. Because the first plate marking on my left homing machine is 3/8". A quilter will know she needs 1/4" and will judge whether or not a left homing machine is for her.
But then, I was using mine a few nights ago. Sewing off the edge of a twill pocket flap with a zig zag to mend it. A drop 1/4" HIGH with nothing else used to level the foot. And only riding on the left feed dog. And it still made a satin stitch I could reverse with pride.
