Yesterday I went to a workshop Japanese Papermaking at the Institute for Adult Education in Utrecht. It was thaught by Akira Matsumoto. He introduced us to a method how to make good quality of paper, by using empty milkcartons. By adding all kind of "ingredients" like tealeaves, fibers, dried flowers, straw, small leaves and sticks, glitters, small pieces of material etc. you can personalize each sheet of paper.
I bought a deckle and mould from Akira so I can try it at home. Hopefully shortly I will find time to do this and will show it on my blog. Too bad I didn't make pictures during the workshop.
