I got a whole mess of cloth diapers from my sister (they are washed and ready to go for when baby gets here), and I have the majority of it figured out except for these pieces. I also have tri folds, liners, and covers, so I'm just not sure how these fit into the equation or if they're a different type of cloth diaper on their own. I would ask my sister about it but she's given me false information before so I dont trust it. It's a little hard to tell in the picture, but at the top and bottom it has one snap, and one piece is longer than the other. Can someone explain how these work? If you can include pictures on how to use them that would be a bonus (I learn best by seeing it).
