i read somewhere that some people use the microfiber towels you would find in the automotive section or walmart, folded in three, as a doubler. So i tried it, so far, so good. But what is the benefit of this and how are you supposed to care for the microfiber towels? I got some training pockets from a lady that could be stuffed to make them more like a diaper. The liners she gave me did not hold enough and he wet through, so i went and got a few of these towels and tried them a few times. What are the benefits and draw backs of using these?
