Re: cause of homemade diapers wicking through threading?
The lady that owns DSS also owns Peachy Green and uses the same PUL in her products. They are high quality, but come to think of it, I haven't used her PUL with castings yet (I am half finishing dipes for when I TTC and DS wears FOE bound trainers at night).
You want DWR (durable water repellant) or Nikwax brand. I hope you can make them work. I know how frustrating it is to put a lot of work into something only to find troubles with it.
