Thanks Guys.

I have looked into buying the bamboo fleece and PUL on snaps.

But for my first attempt I'm going to use microfleece with towelling inner. Hopefully Spotlight have some sort of waterproof fabric that will do the trick if I can't get PUL.

If the pattern works out I am going to buy some bamboo to make some boosters.

My DD is nearly 2, and my last bub, so can't really justify the expense of purchasing a full set at this late stage.
