I prepared a couple of journal pages a couple weeks ago, using a method suggested by Jillie at Craftster.  I stuck sticky notes to the pages to mask off “blank” areas, and painted over the pages, then removed the sticky notes.  Jillie uses these squares for items on lists; I haven’t actually used my prepared pages yet.

This first one was simple purple watercolor painted over the sticky notes.  The background was left white.

And this one was a two-step process.  First I painted the entire page lightly with green watercolor.  After it dried, I stuck the sticky notes on, and sponged the whole thing with a darker green acrylic paint, diluted with water.

I used the same sticky notes for both pages, and ended up with these super-cool-looking Post-it’s when I was finished!  I have never been able to achieve this sort of edgy effect for scrapbooking projects, so I think I might try preparing some pages using scraps of cardstock stuck on with Post-it glue stick, and see if I can maybe end up with some scrapbooking/cardmaking elements as byproducts of the page preparation process.
