Orikane is the art of dollar bill folding, similar to Origami or as some say 'Moneygami'. When we were married we received many cash gifts. I think this may be more customary in Germany and also due to the fact I was moving. The money was not simply placed in an envelope - it was presented. We received a 'cactus', which was a cucumber with money sticking out in every direction, a 'shirt' that said they'd give us the shirt off their back, 'butterflies' with homemade jams, and many organaza bags filled with notes. They were all very unique and memorable.
I was looking for creative ways to give money with an orchid and art work when I came across the Dollar Artist.
These sites look wonderful, however I didn't have much patience with tiny folds - and the fact that Euros aren't the same size as US dollars, so I resorted to the old stand by - hearts. I think it turned out nicely.
