OMG was I ever right about the smelly butt.. I nearly vomited... GROSS.

Can anyone point me in the right direction on how to fold a flat nappy type thing for a boy? DS is out of nappies now (I know.. unbelievable right.. but hey, its been five days worth so its pretty good going I think) but I wanted to give flats a go. I have the old style ones here that I used as chuck rags when he was a baby... will they do? I have a snappie thing and covers, so I'm guessing as long as I got the folding right, they should work.
Problem is.. have NO idea how to fold.. lol
