I got some Twinkletoes Diapers (from etsy) bamboo/zorb inserts from a Bumpie last week.
I just wanted to spread the word because they're FAB. I'm using them in a Thirsties Duo Wrap cover and they're just as nice as the Thirsties brand stay dry inserts only they cost less than half as much.
I'm also using them to stuff my BG pockets since they dry better than the microfiber. (It's so humid here the mf gets "sour smelling" because it never seems to dry.)
Anyhow, check them out if you're looking for a good, inexpensive and very absorbent WAHM insert.
