A set of kucca cloth diaper covers purchased about 3 years ago: 2 size M and 1 size S. Size M: I didn't see any stains or fraying, but I feel like the characteristic moistness of new organic cotton and its water repellency have been lost. I remember washing them with Made in Earth powdered soap. They show signs of use, so please refrain from purchasing if you are concerned about this. Size S: There are stains. My child was slender, but thanks to the wide belly band, I was able to use them with peace of mind. All of kucca's diaper covers are adorable, which makes me happy. They are very cute worn with just an undershirt in the summer. I think the patterns are lovely for both boys and girls.
