I couldn't get the link to work - will try again later.
I bought a diaper kit and think it was slightly a waste of money. While it was helpful to know what to buy - it didn't come with a specific pattern so I ended up going by the seat of my pants anyway. Also I have found that it is cheaper to just buy the material wou want to use to make the diaper.
I made a cover with cute flannel on the outside and plain white PUL (can't see it) on the inside.
