I use these tissue flowers as backdrops in photos and as hair ornaments and have also tried to make a headband from them.
One day I would like to make lots and lots of paper flowers in many different colours, enough to make a full backdrop.
On my pinterest board is a collection of various ways to make different kinds of paper flowers:
I must admit that I did not follow the instructions found on that page for the flowers in these photos but instead I used the method I remembered from when I was a child in Japan. We would make the flower pom poms to celebrate special occasions such as graduations, the first day school ceremony, etc.
Whereas today, I use these paper flowers for hair ornaments and for backgrounds for my photography.
