I made my own one-piece cloth flannel diapers (with Velcro, and an attached waterproof outer layer) -- actually, I bought a few, to see how they were made, and then bought a couple of yards of fabric to make my own. The fact that I was not supporting a corporate monolith (except perhaps for the makers of the textiles) kinda made me feel good. When Spud grew out of them, I bleached them and sent them off on the recycling truck, in a (reused!) grocery bag labeled TEXTILES.

But then, did you know that one can make ones own menstrual pads, as well?

Used diapers went into a pail that contained a small trash bag filled with water, a little bit of vinegar, and some lovely scented orangey stuff. Pail lived in bathroom. Take used diaper into bathroom, flip potential poop into toilet, place diaper into pail. When pail is full (usually once a day or two), lift out bag, poke hole in bottom to drain into toilet, flush, and then take the diapers downstairs to the washing machine.

It's WAY less gross than cat poop.
