I used my 'blind heming foot' the other day and was not impressed. Ended up putting my open toe foot on and was very happy with the results. With the first foot could not really SEE what the machine was doing.....with my open toe foot could see exactly that I was stitching in the ditch on the top, from two feet you could not see the stitch line at all and once the quilt was washed the stitch line totally disapeared from view. I also used a 50 wt thread which helped the stitch line disapear into the quilt.
