woollen nappy wraps (shorties/longies?) - please can someone explain?

[Miaou]

So - you knit a wrap, then lanolise it, and it works in the same way as a Motherease wrap, is that it?

What yarn do you use - does it have to be 100% wool?
How do you lanolise it?
Where do you get the stuff to lanolise it?
With longies, do they just wear them as trousers, straight over the cloth nappy?
Do they leak at all, or have a shorter "timespan" than ordinary wraps?
Anything else I need to know?

Am a keen knitter so would love to have a go at this (and have found some patterns on Ravelry )

Ok.

How to lanolise here

You can get solid lanolin from pixieknits or underthegooseberrybush, liquid lanolin from bumfluff, and wool cure (lanolin and wash combined) from kittykins.

They work by absorbing some of the wetness and letting it evaporate over time, the more they have been lanolised, the more waterproof they are.

They work as a normal wrap would, so last about 12 hours. Trousers are just over the nappy, yup.

Compression can make them feel damp (so a tight vest over the top/car seat/tight jeans) as it pushes the wetness through faster than it can evaporate. But changing the nappy regularly so it never gets completely sodden, and them being well lanolised pretty much eliminates that. DS was in wool 90% of the time by the end.

After the 12 hours or so you just hang them up to air out, and they are fine to use again the next day. Once they start retaining a smell then they need washing. Relanolise once a week to start with, and then monthly/as they start getting damp quicker.

The lanolin mixes with the wetness to form a sort of soapy stuff and it makes them self cleansing (I think)- hence them airing out and smelling fine again etc.
