I'm considering replacing all of our microfiber inserts with pad-folded flats, but would it be safe to sew them so that they stay folded? I might be too lazy to fold them every time before stuffing. I was considering tri-folding prefolds, but I think pad-folded flats are still trimmer. Also, would the basic birdseye cotton flats from kelly's closet be absorbent enough?
