especially cloth ones. I love to dry them on the line so they smell so fresh and clean before I diaper my little ones with them. I'll use disposable but my favorites are cloth and I especially love using the cutest diaper pins I can find with duckies and baby bottles on them.
My mom had the yellow ducky diaper pins and the blue teddy-bear diaper pins she used on me. On occasion she used just plain old silver safety pins, but mostly it was the babyish yellow and blue baby diaper pins.
