I recently started trying out flat cloth diapers. I like how they feel, and I've learned how to fold them several ways, but I'm running into a problem. No matter how I pin them, they always feel loose, even under plastic pants, and as I move they fall down. I think the problem is that, even if I pull them snug around my hips before pinning, the cloth naturally pulls to the far ends of the pins, adding an extra inch or so to each side. Does anyone know how to avoid this? Thanks!
