I haven't assembled one or used them in class yet because I am waiting to be closer to May 5, Boy's Day in Japan, when this kind of symbol is used. I was happy with the quality of the paper, because I feared flimsy, and I didn't realize that scales are cut on 3 sides ( still attached) which adds more interest. This will be a great treat toward the end of the school year. We can research how they are used in Japan. I had trouble with diffusion paper in the past, so I hope this time it will be easier to get colors to flow together. I think we were impatient and used too much water last time. Thanks for the cultural diversity option.
