The major problem I had with the kit were the instructions. The only colored images are on the box, and the instructions can be difficult to read at first. Personally, I double the length of paper I use for every project from here, because they are ridiculously tiny if you don't (they're all supposed to be gift tags I think, but the last thing I want to do is make tiny things my first time). So far, there seems to be enough paper to double it, but I haven't finished everything so I could be wrong.
Honestly though, if you're buying this online, it's not hard to google some instructions or find a video (way better than written instructions anyway). I'm doing all the included patterns for practice.
The supply of paper seems good (I'm a newbie so I'm not sure how far my word goes). You're going to need pins to stick into the cork board that is provided. Otherwise, everything else seems to be included.
