These large squares of fabric become a diaper once folded in an ingenious way. It will make you fall in love with the ease of cloth diapering. Both simple and comfortable, the stretchy flat is the easiest to wash, and reminds us of our grandmothers way of diapering (with a little touch of spandex that makes it a little more modern)! All of our flats work well with Snappi, Boingo or Pins. They also all have a 4 way stretch for a snug and trim fit.
