I agree 100% with Boston1954. Cotton ravels so much I would rather have a full 1/4" seam especially in quilts that are going to be used and washed often. You can always add on a border or two if you feel it is not large enough at the end but if your seams are too narrow and you start to fray you have major concerns. I never seam a scant 1/4" . I have tried and wound up fray checking my seams and that is not an option I want to do again.
