I really wanted to take some extra class to learn a new technique, so I picked up the "Assembly hour & garden" brochure. I have no clue why it has such a strange name, we are not in a garden and the classes take about 4 hours for 5 Saturdays.
Anyway, going through their brochure there were options such a making your own bento box out of glass, Japanese scroll making, rap music class, machine sewing and, my personal pick, paper making!
I have always wanted to know how to make my own paper as my main way of making work is print making and sometimes finding the right paper for pressing my prints on and for what you envision is horrible, especially in NL (Japan is paper heaven!)
