Here is one of our paper designs we call Oribana, made without using any glue from uncut squares and rectangles of paper.
This oribana* arrangement named "Enticing", we created recently, was folded with marvelous handmade Japanese paper "Moriki Kozo" to mark the 1400th Birthday of washi (handmade Japanese paper). It was the year 610 when the technique of making paper was brought to Japan by Buddhist monks, as they say.
We will be teaching this very Oribana arrangement on our workshop this June here in Toronto, in frames of the Washi Birthday celebration under the aegis of The Japanese Paper Place.
If you will be in Toronto in June and happen to be interested by paper arts - we welcome you to join :-) Some experience in origami will be helpful, but not essential.
More info and registration at The Japanese Paper Place website.
UPDATE of Jan 21, 2011: We just released eBook "Enticing Paper Roses" on how to fold every detail of this unique oribana design – flowers, stalks, leaves, a vase and then unite them into the entire composition!
