I have ordered mine from http://greenmountaindiapers.com/
Now that I have used my diapers well and are now getting nicely stained I'm reading up on lots of ways to "whiten" the prefolds and inserts. My favorite way that I've come across is sitting them out in the sun, and just before they are all the way dry, pop them into the dryer to lessen that crinkly feeling.
I'm also on payday going to by Bummis Bio-Soft Flushable Diaper Liners from green mountain diapers. I'm super excited about these. I'm one that once something gets dirty I need to clean it. And going out into public and cleaning a poopy diaper wont be well received by the public. So the liners, I'm sure, are a God sent! Oh payday! Why can't you be today??
