I just move my needle over one click or yes run the foot just over the edge......I know that I tend to over sew my seams, meaning my seams are over a 1/4", so my pieces and then my blocks are too small....so I really concentrate on sewing a scant 1/4" which is yes between 1/8 and a 1/4". I have found I would prefer my blocks a little big and have to trim down to having them too small and having to rip out seams......This is especially true with points, for them to Really look good, then need to be dead-on....
