How can I find the Webjournals created in iPhone on my iPad in the iCloud ?

In iPhoto on an iPad it is possible to create "webjounals", containing photos, videos, text and more in the form of "projects". I can then allow others by email to view them on their macs, computers, iPads etc. But I can find the original webjournals only in the specific app I created them in on the specific iPad. Since they are supposed to be in the iCloud somewhere (therefore sharing is possible), I should be able to find them there as well. But I cannot; how can I ?

I hope I have made myself clear enough.
