We like the pre folded the best. They are thicker and just the right size for a shoulder. The pre folds we use are the same thickness through the whole diaper, not just in the middle with thin pieces on each side. My DD said she thinks they are Green Mountain brand. I sewed four regular thin single fold diaper together to make one big diaper for light wraps for baby in the car seat. It's just enough to keep the chill of the AC off the baby.
