What do you do for the absorbant part? I've used cotton flannel, but my homemade ones don't do NEARLY as well as my various WAHM purchased ones. any ideas? For the bottom, I'm looking for something like one I purchased, its a fulled knitted wool. I almost always just use quilting cotton for the tops. Another bottom option (it works well, but I prefer all-natural) is that no pill mini fleece stuff. (I admit, it makes a good pad, but I just prefer everything to be all natural.
