Am I missing something here? I've never worried about 1/4 inch seams.... I just have a foot that is close and stay with that width. If I do everything the same, what difference does it make. I can live with a quilt 3" smaller than the directions said it would be. If a piece in a block is a pinch longer, I lop it off. I've never understood why 1/4" is sacred. I'll tune in every few days to see what I've been missing.
