I have done it! I have actually managed to make cherry blossom without resorting to glue.
It was mainly to do with the material that I used which was synthetic juban material that I brought from Ryu Trading frequent sales. At first I thought this would be too stiff for cherry blossoms making but as it turned out it was good! Somehow between the stiffness and the synthetic properties, I was able to create the desired heart shaped petal.
The process is still time consuming but nevertheless the results speak for themselves.
