This great model by Mio Tsugawa can really play up any kind of paper. The only BUT is the time needed to make it: 48 folds, about 7 minutes for each module, plus the time to paste all together. Consists of 30 modules, size 7,5*7,5 cm. The paper was presented by Mio-san. You can order the diagram here.
Note: The original model have "pyramids" in the "three-module-intersection" (the no-flower part), that's why it seems more round.
