Hey ladies!

I have just dug out my sewing machine and decided i am going to make some nappies. Just a couple of pockets, as that is the type I find the easiest to use at the moment.
I am going to order some PUL today! BUT just wondering, for those of you who have made their own MCN already, what did you use as the inside lining (as in the bit that touches babys bum)?
The pockets that I bought and have been given are fleece on the inside. So, could I just go to Spotlight and get normal polar fleece? They still have some, but not much as its going out of season. I've got a whole lot of Sherpa Polar Fleece at home which I bought for something else a while ago and never used. Its very soft. Anyone know if this would be appropriate or is it the wrong type of polar fleece??
