SarahKat convoed me the other days after I wondered who else was posting tutorials for various crafty adventures on their blog. She's posted a two part tutorial on making paste papers on her blog (Part1, Part 2) which looks like it could be reminiscent of finger painting (and loads of fun!).

Gemmafactrix also recently posted a tutorial on her blog on Adventures in Papermaking and creating your own deckle screens in custom sizes!
