I have had some success making pocket diapers with a hidden pul layer and outer layer of flannel. I know you are not meant to, but I just love the cute prints and how soft they are!
When I buy my flannel I pre-wash it with fabric softner (seeing as it will be on the outside, I *don't* want it to absorb). Then I use a micro-fleece inner and hidden layer of PUL with the flannel on the outside. I use FOE to fasten the two together - and hey presto a cute diaper
Now I also have some atsko (I think that's how you spell it) spray, (water resistant) and I've used that on some of the diapers I did use FOE on. All in all it's working pretty well - I sometimes have some very light wicking/wetting on the outside (more dampness really) but I figure that just helps me know it's time to change her
It is also worth noting that we live in super-dry Colorado, so I don't know if this would work as well if you lived somewhere where there was moisture in the air (although it rained for TWO days recently - two days - I almost went out of my mind! And I come from a country where 3 weeks of rain isn't unusual!) Anyway even after all the rain they were working fine (although we were having difficulties getting everything dry).
I'm going home for 3 weeks so I'll get to try them out in our super wet winter weather - I'll let you know how it goes.
Incidentally diaper making is so addictive! I made an AIO over the weekend that was so soft and cushy *I* wanted to start wearing diapers
