if you buy the PUL through the website for donating sanitary supplies for developing nations' girls, that charity gets a percentage of the cost. look up thread here on Days for Girls. i have found as mum of 7, grandmum of 6 that terry cloth is the best. Works well even if you don't use PUL. buy hand towels, fold over top about 3-4 ", cut a hole size of baby's head, leaving shoulder room, bind with ribbing or stretchable tape.
