I'm just going to type these out as they come to me, so please bear with me if they don't make sense.
(And please feel free to move this post if I put it in the wrong place.)
Is the 'rise' of a nappy the measurement from the front to the back?
Which fabric is best as a waterproof outer on an AIO? The BGs have PUL, but the Happy Heinys have laminated polyester - is this also waterproof?
Which fabric is best on the inside of a nappy (next to baby's skin) to keep them feeling driest for longest? Are there any that draw the moisture in better than others?
Is 'wicking' drawing moisture away, or leaking?
Which fabrics are the most absorbant - for stuffing pockets, etc?
What is an AI2?
I know some of the answers will be down to personal taste.
