Use a regular foot -- not the SID foot for the 1/4" in design. The SID foot has a guide that will hang up on your fabric when you go out of the ditch. I used a regular foot, aligned the left side of the foot up to the seam, then adjusted my needle to make it 1/4" to the right. Try marking a piece of paper with two lines, 1/4" apart, and line your needle up there. The Accufeed idea is a good idea however, it just doesn't work well in all cases. If you pin well, then you won't have a problem.
