Hi girls

I am kinda new to all this MCN business, am loving it but get confused sometimes!
I have just purchased some Happy Heinys and was reading a bit more about it and came across this...

Should the fleece roll out? Yes it should roll out. Do NOT try to roll the fleece in. This will cause wicking if you try this
How is the fleece rolling out and where does it roll out of?

Sorry if its a stupid question, but I have no idea

Thanks x
