Andromeda123 is sick
Did you put them in the dryer?
Or did you air dry them? I heard they last longer if you air dry them.
Sometimes
I used prefolds with covers. I would usually dry the prefolds in the dryer, with occasional sunning to remove stains. The covers were mostly air dried, although did go through the dryer occasionally. The same prefolds and covers lasted through 2 babies, and while the prefolds seem like they could be used another 5 times, the covers are probably about done.
